Domenica Brown I would. At least the one before this one because there is a lot of back story going on between Sin and Con there.

I am really sad to see this series concluding, although I am happy to see everyone get a satisfying ending. To be honest, I wasn’t that enamored with either Sin or Con when I met them in Ecstasy Unveiled. I didn’t like the closet hookup, and the uneventful sex; and I wasn’t sure I could buy them falling deeply in love in their book. But, I figured that Ms. Ione would have something up her sleeve to turn things around. And she really did.

Sin is a hard person, toughened and disappointed by life.

Sin has been a very very unlucky girl.
Being the only female Seminus demon, she has lived a very lonely life as a paid top assassin. Until recently only her brother Lore knew about her existence and he was trying to protect her as much as possible.
Lately the other three bothers found out about her and they try to protect her in every cost -especially Shane who has already lost another younger sister.

So, Sin is a Smurfette . I just love the following quote from the previous book “Ecstasy Unveile

This book was more of a caugh in a moment buy, so I honestly didn't know what to expect. And to be honest, I only read the first book in this series, so when I started reading this one I wasn't exactly sure what was going on, since the story starts with the heroine and hero already knowing each other and to say their relationship is simple would be the understatement of the year. They've slept together before, briefly, and since Sin is kinda responsible for the illness that's killing 'his kind' ...more

Dear Con,

As with Lore, I would steal you, if I could. But, once again, my loyalty and love for Rhonda prevents me from doing so. Just know that I love you. Now, I don't want you to suffer, so try not to anguish too much over the fact that I can't have you.

Besides, like I said before, Shade would just be so painfully jealous that I don't think I could handle it.

Love Not Drugs,
Leah

5+ stars – Paranormal Romance


Abso-freaking-lutely AMAZING !!!!


I laughed my ass off at Sin’s self-deprecating humor:

Con slid her a glance, one that was almost approving, and for some reason, she felt like a happy puppy that had been praised for piddling outside instead of on the carpet. Annoying.


And the cover is just like the book...hot, HOT, HAWT!!

This book is about Sin and Con. They have both already been introduced in the story and have captivated us for a while now. What is great and different in this book from the previous ones in the series is that

Actual Rating: 4.5 stars

Within this series, I think this one might be one of the best books, even though I really like them all.

The Demonica series is amongst my favorite Paranormal Romance series. The world, characters, story lines and romances are unforgivable.
I value and appreciate the relationship between the brothers and the bonds of family that they preserve. In this book, it can clearly be seen how much stronger one can be with the support of your love ones.

Worth it.

The old saying goes, "It's been a great ride" and may I add a damn sexy one too! When I reflect on the Demonica series by Larissa Ione, I feel as warm and sated as a Seminus demon after an incredible romp in a broom closet at Underworld General! There are two authors that unleashed my exuberant love for paranormal romance: J.R. Ward and Larissa Ione. Ms. Ione has the gift of creating an amazing world of demons, vampires, and werewolves that sucks you in for the ride of your life!

Sin Undone is the last book of the Demonica series by Larissa Ione, but it's the first book of hers that I have picked up. I am a big BDB fan and so you know that any other paranormal romance books are usually shit out of luck. It wasn't the case with Sin.


As the only female seminus demon, Sin is up against a whole load of crap from the beginning. Her touch is deadly and has the potential to wipe out an entire species of warg. Her own assasins are after her position as master. And it seems that e

When we last saw Sin, she'd taken over the assassain's den to hlep save her brother Lore and his angel Idess. Now she's stuck in the den, because any time she leaves, she'll have a giant target on her back. Anyone who wants her power would have to kill her to get it, but if she stays in her den, she's safe from any violence. Unfotunately she can't stay in there forever.

I really loved Con and Sin together, and I liked breaking through Sin's "tough-guy" exterior to her gooey center. Con was an

Conall: n. Hot as hell, viking sexyness, half vampire half shifter. He has the best of all worlds wrapped up in one. (And me wrapped around his finger!)

Sinead: n. Total bad ass chick. Sex demon, full time assassin, and the cause of the Apocalypse! My favorite heroine in this series!

I LOVED THIS BOOK! Even more the second time around. There was plenty of action, emotions, romance, steamy scenes and world-changing events.

I REALLY enjoyed this fifth edition of the Demonica series. Can (Canal?) and Sin were great main characters. Can is a half-werewolf, half vampire, and Sin is Lor’s twin sister, the only female Seminus demon. They make a great pair, especially since Sin reminds me a lot of Tayla and is a very active female lead, leading the assassin’s den at the start of the book. Of course, when everyone in the den wants to take over and the only way to do that is by killing the leader, you have problems. The ad ...more

If story writing was like cooking, Larissa Ione would make The Food Channel itself her bitch with the Demonica series alone.

Another book that made me wish that life would just stop for three days so I could devote all all time to reading. But what matters is that it is done and the final verdict? Larissa is the bomb. BOOM!

Ok, the book is dealing mostly with the werewolf civilization because our leading man is Dhampire (half-wolf, half-vampire). Now, ever since Stephanie Meyer's Breaking Dawn, I

3.5 to 3.75 stars

I liked it and Sin was good at being a badass, Con was hot, but I liked Lore's book more. Maybe Sin is too abrasive or I was tired of all her baggage by the time I got to her book, idk. It also could be because Lore was trying his whole book and Sin, meh, she was passing through life. Also, the whole plot with the wargs/werewolves was so drama drama llama. Those werewolves are all big drama queens.

Outstanding! Excelent Writing. I so enjoyed this story and I highly recommend it to anyone who loves paranormal reads. It was full of powerful emotions and lots of action - I actually teared up at the sad shocking times and my smile got so big with tears in my eyes at the happy moments. The humor kept me on the edge of my seat as I laughed out loud. I didn't want to put it down.

The romance and erotica scenes were hot, I loved the chemistery between Sin and Con. The following statement gives you

This book was beautifully written and really showcases Larissa Ione's talent as a writer. Well done.

I started this book with really high expectations, and they were met. I absolutely loved it, I loved Con and Sin together. A kick ass heroine should have a hero that is at least her equal, or better! Ione paired these two up perfectly! Those of you that have come to know and love the Demonica series will not be disappointed! Enjoy!!

I absolutely loved, loved, loved it. Sin is so feisty, Con is just so god dam sexy, Wraith is so funny and I just love the whole Demon Brothers. I would love to be working at UG!

This story had everything I love, romance, excitement, tears, SEX and great SEX.

Sin is the only female Seminus demon alive who is also master assassin. She has never counted on anyone but herself, including her twin brother Lore. Sin also has a raging libido but can control it because of her tattoo on her right arm called the dermoire. Sin must stay ruthless and show no sign of weakness. But she's been feeling guilty lately because she is responsible for unleashing a virus that's killing wargs, better known as werewolves. If she and her half-brothers, who work at Undergroun ...more

"4.5 stars" Sin Undone, the fifth full-length installment of Larissa Ione’s Demonica series, picks up where events left off in the previous book. We started getting to know Sin and Conall in Ecstasy Unveiled. Sin is the full-blooded, twin sister of Lore, the hero of that book, while Con is a dhampire paramedic who works at Underworld General Hospital. This pair had an inauspicious beginning when they engaged in some sexcapades in a supply closet as part of a bet that Con

An amazing end to an exceptional series.

After reading Lore’s story in Ectasy Unveiled, the fourth installment of the series, I wondered ‘how do I get a Seminus demon??’ Having just finished Sin’s story, I can’t help but think ‘how do I become a Seminus demon?’

Sin was my favorite heroine in this series, which is really saying something because she had some stiff competition from Tayla, Runn, Serena and Idess. In addition to being an overall badass assassin, Sin revealed herself to be a truly ca

I had a terrible sadness come over me when I read the last line of this book, because it was over!! LOL - I loved this book and the whole series, so much so that I bought the entire series for my keeper shelf. I do have to say that I liked the way the series ended with the opening for the spinoff series. Hopefully we will get to revisit the Sem brothers (and sister)
