Three silver fox sugar daddies…
Plus one broke biology student…
Equals two buns in the oven.

The Copeland brothers aren’t just rich…
They’re filthy rich.

And now they’re getting promoted…
From sugar daddies…
To baby daddies.

Colin, Dean’s twin, is the gentle tech genius who touches me like I'll break.
And Atticus lives by a simple code—either they come together or not at all.

I’ve fallen for all three equally.
If I lose any one of them,
My heart would be shattered into a billion pieces.

I can’t choose.
And God help me…
Because I don’t want to.

My two little girls need their three daddies…
With sugar and spice and everything nice.

Atticus, Dean, Collin and Thalassa

[Shelley G · Rating 5 out of 5]

new author this book was extremely enjoyable. thalassa is a struggling broke university student who signs up to be a sugar baby in order to earn money to survive. she clicks the virgin section and is sent an offer by 3 much older billionaire brothers, dean, colin, and atticus, who are searching for something different to combat their boredom and stressful lives. they are tired of the same type of woman on the app but seeing thalassa's profile which seems real and authentic including it being her first time something draws them together. she accepts their offer and they all spend a weekend together. when its over they go their separate ways but the men feel drawn to perhaps interact with her further. the story follows what happens from her signing up on the app to interacting with them sexually to many events that happen afterward. surprises happen, traumas are exposed on multiple ppl, boundaries are crossed, lives are intersected and changed on multiple levels. a convoluted and complex mess of multiple lives trying to come together in some meaningful way while also dealing with the fragility of life, the complexities of emotional baggage, physical health, mental scars and life choices that cause reactions. this is not your boy meets girl falls in love story. this is a messy cocktail of loving more than one person at the same time, secrets, shadows, surprises, plot twists, emotions and ultimately a coming together in compromise compassion caring and love plus a best friend who has your back no matter what.

Atticus, who was CEO of the family firm, took early retirement and now struggles with boredom.

Dean has taken over as CEO and sometimes wonders how Atticus managed to be ahead of the game all of the time.

Colin, the CTO of the company, a computer nerd and wiz, struggles with the failing systems, and is constantly putting out fires. If only Marcus, the CFO, would just listen to him and let him purchase a newer model which though expensive would greatly benefit his family's business.

Thalassa, a struggling student, is told by her friend how she could earn extra money if she were willing to go down that route. Is she willing to take that leap?

When Atticus sees Thalassa's profile pop up on the App, he is intrigued. It's the first time in a long while that a genuine woman has caught his attention. He is interested. Would his brothers want in on the action? A holiday weekend of fun, no strings attached, then back to the daily grind?

That may have been their intentions, but Thalassa has a way of getting under their skins; she just fits with all of them. None of them can get her off their minds. Can they walk away, or do they covertly work behind the scenes, making sure she is ok? When she has an accident, the brothers are there immediately. They will be whatever she wants them to be, but does she want them, or is she scared by how much she wants them? Will her fear stop her from taking another leap into the unknown?.

A hot RH story

This was a great RH book. Great, albeit a bit predictable at times, plot, flowing, with enough drama to keep one’s interest. All the main MCs were very well developed. Thalassa is a college student and under the encouragement of her friend Arabella decides to file a profile in Just Desserts app, to offer herself – an her innocence – as a “sugar baby”. No attachments, mutual fun, a considerable nest afterwards – a transactional relationship. Enter Atticus, Dean and Collin. The Copeland brothers. Three highly successful men in their own right and approximately twice her age. Each with their own distinct personality, strengths and vulnerabilities (past and present). Thalassa also suffers from past trauma. The attraction is there from the start – more than the physical part, which is undeniably explosive. So, what was supposed to be a fun, one-time long weekend, turned gradually to so much more (amidst mild (…or not) stalking, a skiing accident, an unexpected pregnancy, a corporate internal battle and so much more). I loved how the men tried their best to respect her boundaries and being willing to meet her needs, and I am glad Thalassa, despite some knee-jerk reactions due to her fear and her young age, was also able to recognize and accept her feelings and what matters the most. They all complement each other well. I also loved how supportive, protective and non-judgmental their close friends and family were. 5 stars.

Virgin Thalassa Howard was a college student trying to make it on her own. She came from a poor background and was barely scraping by. She wanted to go on a ski trip with her girlfriends, but she didn’t have the money. One day, her best friend Arabella told her how she made money and offered to sponsor Thalassa while she pursued her own Sugar Daddy. Except Thalassa got an offer from Dean, Colin, and Atticus Copeland, three brothers who wanted to be her Sugar Daddies for a weekend, for an insane amount of money, and she agreed. What was supposed to be a weekend soon became more.

Filthy Rich Daddies was a steamy, reverse harem, older men/young virgin, billionaire story that in my opinion accurately described the Sugar Daddy/Sugar Baby transactional relationship that can benefit willing participants. It is a win-win for both parties because the Sugar Daddy gives money or gifts to the baby and the baby gives the daddy the intimacy or companionship they want. In this case, the amount of money Thalassa would have been given would have paid for the rest of her tuition, her ski trip, and she would have been able to send some money to help her parents. The story was written respectfully and showed consent at every step. Thalassa and Arabella also had a system in place to ensure her safety. I enjoyed following the love story develop between Thalassa and her men and recommend this book.

I really enjoyed this story about Thalassa who is a 24-year-old, college student and is in her final year of college. Her roommates and group of friends are planning on going on a ski holiday in Aspen, that is going to cost $20,000, but she doesn’t have that kind of money. When her roommate tells her about a dating service called Just Desserts which allows sugar daddies to date women who need money for some reason or rather, and that’s where she meets brothers. Atticus, Dean and his twin brother, Colin Copeland, who are billionaires, and are willing to help her in a mutual appointment. What they don’t plan for is having feelings for Thalassa and learning, six weeks later, that they are going to be fathers. I really enjoyed the story and how it flowed and how it had a depth that kept me wanting to read till the very end and enjoyed their happily ever after.

So this one hit a little different for me. Generally I expect reverse harem romances to be hot, with a good storyline, maybe some angst, and a feeling of found family. This one has all that…. But it’s also really deep. There’s some trauma that multiple characters have in their pasts that have to be dealt with, and is discussed and integrated into the story with great care and great sensitivity. If you have issues with birth trauma you may want to steer clear. I don’t think this was discussed or mentioned ahead of time in the front of the book. There’s also a history of water trauma for Thalassa, and again it’s written about with sensitivity and care but if you’re sensitive to it, beware it’s there.
It is a beautiful book. Thalassa and her three men get a hard earned HEA. The story is heart wrenching at times. There were tears (for me at least).

I received an Advanced Reader Copy and am voluntarily reviewing it. Ms. Archer got me again. I so appreciate all the wonderful stories that she comes up with. I will continue to read every book that she writes. This one is a little different. Thalassa Howard is a biology student who wants to go on a ski trip with her friends. Her friend introduced her to a site that allowed her to offer her time (among other things) for a price. Thalassa's profile caught the attention of the Copeland brothers. They had shared women before. Neither of them wanted anything long term. They were busy men with a company to run.

That all changed after they spent the weekend with Thalassa. She understood them in ways no one else had. Now they can't get her off their minds. Atticus, the retired CEO; Colin, the tech genius and Dean, the new CEO, are trying to focus but she keeps invading their thoughts. What happens when Thalassa finds out she is pregnant with twins? Will the filthy rich daddies back down? Thalassa has some serious decisions to make. Will the brothers be there to help her make this decision that could change all of their lives? This book is hot and will keep readers interested. Ms. Archer always gives me RH that I did not know I wanted.

Thalassa AKA SnowLass
Atticus,Dean AND Colin are brothers. They work better as a triumvirate. Atticus is scrolling through the sugar baby site when he comes across Thalassa's file. He sends it to his brothers. Thanksgiving weekend is booked.
The brothers can't see to get her out of their heads. Thalassa has to concentrate on tests and lessons.
On a visit to his dad he gets some sage advice and a little ancient history but sees the wisdom.
Can he and his brothers make a go of a relationship? Will Thalassa be ok with the dynamics?
A story that starts with a woman being sort of guilted into doing something her keen mind can barely comprehend. But as the reader continues the dynamics increase and it's like watching a flower bloom.

This was an absolute cute, spicy story. The three brothers are cute, each one in a different way. Thalassa is strong, smart, funny, and a bit crazy! Atticus is my favorite I must say, I love them all but he was my favorite. The twins Dean and Colin are cute too. I like the story, I wish there was a little less about the company and more about them. Her bestie is amazing. I love when a book has a ride or die bestie with a lot of attitude! The plot was good and the spicy was delicious. I even read the bonus epilogue which was absolutely cute and Spicy as well!!.

I received this book with the understanding that I could leave a voluntary and honest review.

In this book we meet Thalassa, Atticus, Dean & Colin. Thalassa would do anything for her education including going without. When she finds out one of her friends has found a way to take trips and other things without a job of her own. Atticus, Dean & Colin are so rapped up in their businesses finding a woman just isn't possible. At least to give her any real time and attention. Will one website bring them all together for a HEA or will this just be a one time thing?

Amazing story by this author. I would highly recommend to anyone.

Absolutely beautiful!

Sometimes you read a romance and it's all steamy sex and some good characters that you like and make you hope its a happily ever after.

Other times you read a romance novel, and yeah the steamy, sexy bits still have you fanning yourself...but you find beautifully flawed characters that you somehow relate to. You get pulled into their story and can't put it down till you've learned all their secrets and watch to see if they heal and grow!

And sometimes, the writer floors you with something that you grow from!

Well done Liz Archer for taking this story to the next level!

[Lennon · Rating 4 out of 5]

This was such a fun, spicy, and addictive read! Thalassa is smart, hilarious, and a little chaotic—in the best way. Her connection with the Copeland brothers is instant and intense, and I loved how each of the guys brought something different to the table (Collin was my favorite!!).

The plot was light but engaging, with just the right mix of drama, steam, and a sassy bestie who brought major ride-or-die energy. Overall it was a deliciously fun reverse harem with a bonus epilogue that made me melt.😍

If you’re in the mood for an easy, spicy, sugar-baby RH with heart—this one’s for you!

[E Williams · Rating 4 out of 5]

This is definitely a bit deeper than the usual auction/reverse harem novel. All of the MCs are interesting and enjoyable characters. The background story regarding the business, the embezzlement and also. the environmental study and of course Atticus's backstory, definitely flesh it out making it more substantial. At times the writing is really very good

All 3 MMCs are well drawn and the FMC a girl named after the sea but who is terrified of it, is a likable character.

I enjoyed this and I'd like to read a book about Arabella.

[Judy · Rating 5 out of 5]

These characters were so awkwardly beautiful, I couldn’t put the book down. The way the brothers flowed around each other and battled up for the girl they didn’t see coming was hilariously perfect. Aside from the why choose hotness, this story truly feels complete. The touch on stress, overworking, fears, and trauma was written incredibly well.
The heat level is off the charts.
The emotional level is connecting.

Great reverse harem with 3 brothers and 1 woman. Love learning more about the female character Thalassa and the fact that she has a life outside of just being with the guys. She is exploring options as a virgin sugar baby. Each brother (Atticus, Dean, and Colin) have very different characteristics. Their interaction really works.

Love the fact that Dean and Colin are twins and the fact that Thalassa is pregnant with twins.

Update, a few days later. I tried two more of Archer’s books and was hoping for the same enchantment, but they weren’t close. So I went back and looked through my ratings on more of her backlist, and have to say they either really wowed me or left me cold. Sigh.

Original review:
I think with Archer’s books you just have to ignore the titles and covers and read them anyway. She’s writing some of the best contemporary RH romances I’ve read in quite a while.

Pure escapism, of course, but there is also human-ness and emotional truth along with the deliciously overwhelming sex scenes. It’s the best kind of smut there is.

[Merry Jelks-Emmanuel · Rating 5 out of 5]

When she became a sugar baby for the Copeland brothers Thalassa had no idea the direction er life would go as a result. This heartfelt story centers around self-healing and building a relationship they never saw coming. It is a well written story that is inspiring and had me connecting with the characters all throughout it.

She just wanted a great vacation with her friends. It was suppose to be only one weekend for all of them. The connection that they feel for each other is a strong one that they just couldn't fight. They are a bit heavy handed but its the only way that they know how to do things. Their worlds have a lot of ups and downs but together I think they can do it.

Student Thalassa (FMC) is struggling for money but a opportunity given by a friend gives her a way out to become a sugar baby to three billionaires (Atticus, Colin and Dean) for the weekend giving them complete access to her for 3 days. After that things don't go according to plan and all of them are left with more than just memories. A pregnancy. This book follows how they cope with that and the guy's attraction to Thalassa. Sweet in places and steamy with a few sad parts too. Loved It.

[Kassi · Rating 5 out of 5]

Worth the read

Whew, this book! 🥵 The chemistry between the four of them is off the charts. I loved how they just click—no pretending, no masks—just raw, messy, beautiful connection. They see each other's jagged edges and still choose to lean in. Each one brings something different, helping the others grow and heal in ways they didn't even know they needed. Seriously, the way they love? Whew. Give me more of this kind of connection. 🔥

Filthy Rich Daddies

Filthy Rich Daddies by Liz Archer is a Reverse Harem Daddies book.
Thalassa is a college student that turns to the app "sugar baby" when she needs money at her friends council.,
Tic, Dean & Colin are brothers that run a big business. They each have their own reason for using the app sugar babies.,
Liz, this was a cut above most reverse harem books I've read. Thank you for the story & the characters. DC

Virgin FMC/ why choose/ MFM/ MFMM/ age gap/ pregnancy/ found family/ HEA

Trigger warning: death of a loved one/ stalking/ death of an infant/ PTSD/ trauma/ health scares

This was ok but a lot of it felt like filler. I know there were 4 MCs but it felt like we didn’t get the FMC’s POV as much for some reason. Also a lot of the heavier talks didn’t happen until much later in the story so it felt a bit unbalanced plot wise.

Thalassa And the Guys

Rh, v, science nerd fmc, 3 brothers, sugar baby?. Thalassa is kind of a sad character. She was upset she had no money, she was upset things happened on her one night, she never really is truly happy and in moment. For RH it was very mild in spice. And I don’t feel it had tons of chemistry but it did have love and a different love with each guy. It had a great HEA.

[Trish · Rating 5 out of 5]

Intense, but soothing!

The whole story is so full. Each of the main characters has such a deep, involved history. When she follows her friends advice to use the dating app, she never expected to be with three brothers. Then she finds out that she's pregnant. Love how each brother does something sweet and meaningful for her family, behind her back. Loved the rounding up and solving all the problems. Beautiful HEA ending. Trish. A

It's a safe read !
It's nice to pass time, the angst Is just to season lightly and theres no real toxic shot in sight.

It was nice but I felt the feelings were a bit fast paced ? Like I can't explain but in 24h they were like " ooo yeah you might be my person fr fr". Also Just felt like it could've been shorter than all those pages. And one thing that Icked me a bit was that I felt like I was reading about young dudes. They didn't have the usual Mature Sdaddy vibes we usually get.

[Kathryn · Rating 5 out of 5]

Better then I expected

The cover and title are deceiving. This book was really good. I read it in one sitting, and it was a cas eof just not wanting to put it down. This was so much more then a spicy littlerh, which I mean yes it had plenty of spice, but the characters also sold it. They had depth and history, and issues to work out, but this didn't cause too much unnecessary drama. It all just sort of came together smoothly. Highly recommend.

Thalassa becomes a sugar baby for the Copeland brothers so she can go on an expensive skiing vacation with her friends. The biology student has no idea how much it will change her life besides losing her virginity to them. This is an easy-to-read spicy reverse harem.

Nice steamy story with a good flow. The FMC sometimes annoyed me with her reactions but otherwise all characters were interesting and was sad that the book ended. The guys are brother's so don't read this if that weirds you out (not that swords cross or anything!).
