I’ve wanted my brother’s best friend, Leo Santoro, for too many years to count.
No matter what I do, he won’t confront the attraction that burns between us.
It’s time to put him behind me once and for all.
I have no choice but to call his bluff.
And then I will walk away.

The last woman I should want is my best friend’s baby sister, Jillian Banks.

***3,75- 4 "Sinful" stars***

I loved the first book in the "Undone" series... but the second book wasn't what i was expecting!!!
Don't get me wrong!!! I liked this story also but i think that something was missing!!!
I liked both Leo and Jillian, but Michael will always be MY man!!!

But let me take the things from the beginning...

Jillian is Michael's little sister and she was not "too secretely" in love with Leo, her brother's best friend and coworker...
She had thrown herself too many times to Leo

Leo Santoro. My brother’s best friend and partner. Object of my lust-filled fantasies.

Oh I am HUGE fan of brother’s best friend books. I have always loved these stories, they are my kryptonite. I have also read a TON of them, but this fresh little twist was super hot. See Jillian is Leo’s best friend’s sister. Usually when I read this stories they all have the same outline, until now.

Leo is a dominant and his best friend is very aware of this fact. I also loved how when Leo did decide to ac

Jillian Banks is Michael’s little sister. She has been attracted to Michael’s partner Leo Santoro since the men graduated from the academy. She knows Leo is attracted to her but he will not make a move and Jillian has decided she will. I liked Jillian, she is grounded, sincere and intelligent despite the fact she is unsure of her career goals. As strong and confident as she is, there is a vulnerable side to her, and I appreciated how open she was about her feelings.

Leo, poor, poor Leo, I felt so

I really, really, really LOVED this book. Although, I have read this storyline countless times, author Jennifer Dawson writes in a way that makes readers not care. Leo is the sexy bad boy cop who needs a submissive woman. Jillian; the sister of Leo’s best friend Michael, has been trying to get with Leo for years, to no a
This book and substituting for fourth grade DO NOT go hand in hand. Yikes.

3 almost 4 blazing hot and bad boy stars.

This was something else. Jillian has had a crush on Leo for years. Chemical reaction when they first met, but unfortunately he's her brother's best friend so he has intentionally frozen her out. She makes a last ditch effort to get him at her brother's birthday party. She lays it on the line and he rejects her. She is very up front that this is it for her. She's moving on. Leo

Two for two : This is the second Jennifer Dawson book I’ve tried in the past couple of months and the second one I’ve really liked. I went into this story blind, as I didn't realize it was part of a series, but I was not lost or in need of reading the first one to enjoy this book. Note: Of this trio of friends (Leo, Michael and Brandon) I found myself desperately intrigued with Brandon and I want his story soon. Pretty please?

Back to this story - I love that Ms. Dawson can work a well establish

I really enjoyed this second installment in the Undone series about Jillian Banks (Michael’s sister from Crave) and Leo Santoro who happen to be also Michael’s best friend and co-worker. Jillian is 28 years old and she has wanted Leo for too many years to count. He is the object of her lust-filled fantasies and she tried over the year a variety of ways to seduce him. But each time Leo rejected her and continued to treat her as his best friend’s little sister.

Jillian Banks knows there is no turning back, she has been rejected enough by her long time crush Leo Santoro but now she is letting him know she is done. She understands Leo's hesitancy of getting involved because he is her brother's best friend, but she also knows he wants her as much as she wants him.

Leo wants Jillian but as much as she thinks she knows him, she has no clue about his darker side. When he realizes he is about to lose her he makes his move and he plans to push her as any domina

AMAZING!! I think the first scenes of the book at the bar were a ten star read. It was so wholly satisfying to read about a strong woman who was putting her foot down, but who was still vulnerable at the same time. And the rest of the story didn't disappoint in any way. It's not easy to portray a character as submissive while still retaining her independence, fire, and self-respect, but Ms. Dawson pulls it off effortlessly. A wonderful read.

I am a HUGE HUGE of brother’s best friend books, so when I found out this was one I immediately started reading it. I really don’t much to say other than it’s good. You really can’t go wrong with books like this. And I wish someone would sing me Beatles songs outside my window too;)

This is the second book in the Undone series by Dawson and wow it's definitely different then her other series that's for sure.
Since this is the first book I have read in this series I expected to be lost but thank god I wasn't.

In this new series Dawson branches out with 3 guys who are very much dominate. In this book Jillian is tired of lusting after her brothers best friend Leo. It's time for her to either get the guy or move on but what she doesn't know is that Leo kinda has a thing for her

If your life-long crush had a secret life would you still follow him??

Such is the dilemma for Jillian Banks. She's always crushed on/lusted after/loved her brother's best friend, Leo Santoro, but she's giving him just one more chance to take her on or she's walking away. Leo craves Jillian, but knows that she's just an innocent when it comes to his depraved needs and he won't taint her, nor can he change to be the man she perceives him to be.

Leo's best friend's little sister Jillian is all he's ever wanted but he has this other side of him that he's not sure she would be able to accept. She is going to give him one more shot and walk away for good to move on with her life. She pushes the right buttons and Leo succumbs to the lure but what she thought she wanted isn't necessarily what she gets. There's more to her that she hasn't discovered. Leo is one sexy alpha dude and this book is scorching hot.

I hated to see this one end. Just like the first. I enjoyed the characters and hope she continues telling their stories. I am very curious about Gwen and Brandon...(I think they would be an interesting story). Plus Jilli's roommate. I swear there is a story there as well. Keep it up Jennifer! I have waited a long time to read this one. I can't wait to read what you do next in book 3.

Although this is book 2 in the Undone series I have not read book 1 and the events in Sinful actually happen before the Crave storyline so no harm done by reading book 2 first.

I totally dig the older brothers best friend romance and this one packs a punch. Jillian has wanted Leo since the first time they met but he sees her as his best friends little sister and therefore she is off limits.

Jillian throws down one more attempt persuade Leo that she is perfect for him and it works - kinda.

I liked this book and I didn’t like this book. That’s why I gave it a 3.5/5 star rating. Going into this book, I really thought I was going to enjoy this book. I have heard good things about it. The one thing I really didn’t like was Jillian. She was kind of annoying to me. I did like the fact this was a best friend’s sister romance, I like stories like that, but I just did not enjoy this one.

Jillian Banks has been pining over her brother’s best friend, Leo Santoro, for too long and it’s time for her to go big or go home. Dressing up to the nines, Jillian is ready to give Leo a run for his money, and she walks to her brother’s party with a purpose and a sexy sway of her hips. She knows that he can feel the chemistry between them and she knows that he wants her too, but he just won’t take that step, Leo is holding back and it’s driving Jillian crazy.

Plot: Jillian has been after Leo for years but he has spurned her advances; and she has decided she’ll give it one more shot, before calling it quits and moving on forever. She knows there’s something there, but what she doesn’t know is that he’s hiding a rather large part of his life and neither of them are sure if she’s ready to face it.

Well I'm at a loss as how to review this book, I do enjoy romances with friends falling for their best friends sibling. So I took a chance on this for 99¢… I should not have. It started out good but then the author had to mess it up by throwing bdsm concepts in that weren't relevant to the story, nor done well. Then it got creepy and then just sad. This had potential had she stayed on track with her premise and not try to be like so many out there by throwing bdsm thinking more people will enjoy ...more

I've been in a book drought and needed something to save me. I wanted something fun, flirty, and fast paced. This book had it all. I started it yesterday evening and finished it sometime after midnight. I didn't complete it all in one sitting. My life is still way too chaotic for that! I wanted to though.

The two main characters are Leo and Jillian. They are perfect foils for each other. He is measured, methodical and manly. She is flighty, fiesty, and unafraid of her feminity. They have a kind

oh boy what a book LOL yeah this story is great. I'm always a sucker for younger sisters and their older brother's best friends or best friends stories in general because it gives the book an establishment to work with. When the characters have already got a good connection and then fall in love out makes the live story real, in a way its different than your average romance.

I loved this book because between the characters there is nothing off-putting or weird about them which made things sexy a

I absolutely loved this book! We get introduced to the world of dominance and submission through the eyes of Jillian. She's determined to either force Leo's hand into a relationship with her or to walk away from him for good. Force his hand she does! Her last attempt is done in a way that he has to try a relationship with her. Much to her shock, there's much more to Leo than meets the eye. There's some happy times, some hot sexy times, and some sad times all along the way to a happy ever after. ...more
