Kenton Monroe has wanted her for far too long. But Madeline Caldwell isn’t giving him the time of day.

Madeline is looking to break out of her innocent shell, but Kenton definitely isn’t the guy to experiment with. She needs a nice guy, not one who makes her lady business glitter like diamonds.

Kenton has been patient for months, but she won’t bend. Getting her alone on a

4 Smut Scale Stars

Whenever I'm searching my kindle feed...


When I'm feeling the need...


...For a smutty read...


Have no fear.


The answer is ALWAYS clear...


And it's Alexa Riley.

So look no further...


Or do...


It's up to you...

What I am NOT - obviously - is a fucking poet. But I was going for painful and I think I succeeded lol.

Seriously though, I really enjoyed this one. In fact, I think this is one of my favorite AR series to date.

It's one sweet reading, probably one of the most sweet and less erotic by Alexa Riley. And I enjoyed it from the first page to the last. Actually to be precise from the blurb and the warning.

Twenty-two year old Madeline had enough of being a cute little sister of her four brothers. She wants to be a woman, but under their watchful eyes is not going to happen. When opportunity comes and she "wins" a trip to the paradise, she packs up and starts the adventure.

Kenton Monroe is one rich bastard. He

I liked it! I was very patient and waited for the release day and of course once it was live I bought it immediatelly! I knew what to expect, since it AR but there was one plot twist that I didn't see comming. At least not the way it did.

“Is it always this dead around here?”

...And that sentence is probably the biggest lie. Since Madeline is finally free of her overprotective brothers she decides to simply relax and enjoy her time away on vacation that btw. is interupted by her long-term stalk

Another fantastic little AR treat, with an equally amazing and obsessed H! Like I've said before, I adore this series, and the perfect little dose of HQ drama makes them just as PERFECT!!! <3 <3 <3

This book was really sweet with two enjoyable characters and some hot scenes in an isolated island!A little paradise for the horny couple. And the best place to start creating life...Although they got a littl
Updated review June 29, 2o16:

4 stars!

After DNF'ing 6 out of the last 7 books I have read, I decided this book deserved a higher rating. So yes, the hero had sexual experience, but at least we didn't hear anything at all about other women and he wasn't a manwhore. That alone is worth a 4 star. :D

Original review: 3.5 stars

Overall, a sweet and sexy romance. AR fans will love it. Hero was a a great OTT alpha obsessive type I enjoy reading about! Unfortunately for me though, now that I have read so

I loved this one.

Super Sweet - Super Insta-Love - Super Sexy - All wrapped up with a fabulous epilogue...

Innocent curvy naive virgin. Jealous sweet alpha . Instalove. Marriage. Babies. Rince repeat.

It was going okay, I liked Kenton, but then we hit the cherry popping scene and my eyes were rolling so much that I now have eye strain. And AGAIN I had 'Come with Me Now' on loop in my head because they always have to orgasm together.

Argh. These books are all the same basic story and I'm getting a bit bored of it every time. The same system can only work for so long without something having to be chang

It’s Alexa Riley so you know how this goes but this is a good one, it’s beautiful and sweet.

Kenton is the handsome billionaire with the world at his feet. Madeline is the 22 year old virgin with four older very possessive brothers.
Kenton has never thought much about love or marriage that is until he sees Madeline and then he’s gone. It’s insta-love at its best. Madeline wants Kenton but sees him as the rich playboy and she knows he’d break her heart given half a chance.

But Kenton is determi

A billionaire romance that is hot, sexy, and oh so sweet!!! Yes, please!!! The Billionaire and His Castaway by Alexa Riley was the perfect summer read to kick off the first day of summer. Not only was this book such a fun and sexy read but it made me want to go on an island vacation stat.

Billionaire Kenton Monroe has everything and I mean everything including a beach resort and a private island. But what Kenton doesn’t have is Madeline Cald

Absolutely #1 of the series for me. Kenton was everything I love about Alexa Riley heroes . Gone for her from first site.. Obsessed, possessive, crazy jealous and so sweet. I could have choked her brother but I really loved how he took it like a man. Madeline was the perfect balance of shy and sassy. These two definitely burned up the pages. I really loved this one from page one. Perfect.. All the way.

Another sweet and sexy addition to the Alexa Riley Promises series that I absolutely devoured. The Billionaire’s Castaway is a firm tongue-in-cheek modern day take on some of the Harlequin Specials of the past, and the duo delivered it brilliantly.

Enjoyed this next installment of OTT alpha romance from the Alexa Riley duo. Kenton employs Madeline's brothers and when they bring her to an event, he is instantly smitten and doesn't know how to react. Unfortunately, it comes off as dislike to Maddie who is fighting her own attraction to the sexy billionaire. Soon, she "wins" a trip to an island and who does she run into but the mysterious Kenton. Shenanigans ensue. Misunderstandings are had. Sexy love made. One part's logistics had me a littl ...more
**4.5 Stars**

Loved this one! My favorite of the series so far. Kenton was a wonderful hero. I love how he went after Maddie and planned to get her. Maddie was annoying me at first but she came around. I did want to strangle her brother though. It was totally OTT and unnecessary drama. Love the epilogue. My only complaint as usual, is I wish it was longer.

3.5* not Tom Hanks' Castaway STARS!

I enjoyed Alexa Riley Promises #1 but dislike Alexa Riley Promises #2. Hmm... As you can see, I'm back for liking this book. This series wasn't like her other filthy works. It's more focused with over-the-top happily ever after and I don't mind.

Kenton Monroe has been eyeing for Madeline since their last meet at the party. Unfortunately, Madeline has four brothers who works for Kenton and he didn't feel comfortable. Because of his uncontrollable lust, Kenton pre

3.75 stars! sweet and sexy read.
I loved the hero.heroine got on my nerves a bit in the beginning but I got over it.Loved the epilogues:)

safety gang safe
The only thing that bothered me was if he used condoms before or not in his pasts sexcapades.nothing was mentioned only that he is clean he gets tested and he hadn't been with a woman in a long time. usually Alexa confirms first time going bare so I was put off a bit. It's my own personal trigger.

I liked the hero in this one better then the last one in this series.

Super sweet and hot :)

*Matthew McConaughey voice* Alright, alright, alright! Suspended reality for my OTT possessive alpha hero fix and all is well. This'n more than made up for the last book with all that hymen licking and breasts that might still have growing to do and drawing cum hearts on butt cheeks, etc.

We have our standard issue, insanely possessive H who will stop at NOTHING to seduce, knock up and marry our sweet little innocent h. She thinks she won a free vacation by taking a 20 question survey but we're

I loved this book! This is my favorite in the series and I can't wait for more. The story's so good! He's so obsess and I loved it!

It's about Kenton and Madeline, 22. Nothing was mentioned about his age but I think he's older than her. Maybe a few years.

Madeline just graduated three months ago. She had four overprotective brothers who own a security firm together and men aren't allowed to be near her.

Kenton's one of the richest men in the world and he's close to her brothers. They're also worki

Once again, I enjoyed this little novella by Alexa Riley. This is the third book in her Promises series and this series is my guilty pleasure. I don't know what it is, but I can't stop reading these books. They are short and full of insta-love relationships which I usually don't like, but there's just something about these that I enjoy.

Madeline is the youngest of five kids, with her four older brothers being very over protective. When Madeline wins a vacation, she's super excited. It's just wha

This book was so perfect! You won't believe the lengths that Kenton went to get Madeline alone! I loved every minute of it.
This is the first time I will ever call anything that is written by Alexa Riley is bland but what can I say?? First time for everything I never knew she could write with such innocence, I guess my dirty mind is used to her smut filled over the top escape. Don't get me wrong, this book is over the top however there is an element of sweetness and plot is written in a concievably tame manner for AR's usual style. I still enjoyed this sweet read as always.

Fun, sweet, low angst novella about a billionaire H going to extreme lengths chasing a sheltered and inexperienced h. 3.75 stars!

This 'Promises' series by AR is about bringing their own spin to existing romance tropes. Their spin is refreshing and healthy - there is clear communication btw MCs, respect for the other's feelings and of course no other romantic partners involved. In comparison to most older category romances where there are shades of misogyny, slut-shaming, double standards, cheati

I didn't love this one as much as previous books. Maybe it was the fact that the font the publisher used was so huge. Madeline and Keaton were very sweet (haha) together and the sex was just ok. Loved all the epilogues. I want a series with her brothers (or is there one already and I dont' know it).
