Cocksure by K.I. Lynn and Olivia Kelley was a great read. It was my first time reading anything from either author and I really liked the writing style and flow of the book. The witty banter and brotherly ribbing between the hero and his best friend(heroine's brother) was funny af. I loved the plot! I am a total sucker for the forbidden fruit, best friend's little sister love stories.

I loved the hero Niko. He was a sexy firefighter, and reformed man whore

Cocksure is a contemporary romance that is sure to turn up the heat and leave you swooning! A blend of forbidden romance, intrigue, and laugh out loud moments, Cocksure is full of surprises with every single turn of the page.

Everly is finally returning home. After a bad breakup, she wants nothing more than the security and strength of her family and friends. Upon her return, her first stop is a local bar to be reunited with her big brother. When

That’s before I even cracked the book. Then I met Niko. Ooh baby!! Niko was EVER-Y-THANG!! This man was the quintessential manwhore. The kind you have to love because he’s all honest and stuff. He may not remember your name in the next five minutes, but he’s respectful and ish.

But then he’s cracked upside the head when he meets a mysterious woman with whom he shares an electrical connection. I’m talking sp

Before this I’d read only one book from this author and that was the brilliant Six. I’m amazed it’s taken me so long getting round to reading another one.

So I was really looking forward to this, I mean it has the cool title and the brilliant cover plus the intriguing blurb.

Now since there’s already loads of reviews I’ll keep mine short and skip my usual summary and just get straight onto my opinion.

This started really well and I loved and lusted after Niko. He’s your typical manwhore but I l

3.5 Post-it note stars!

So Cocksure is about Everly moving home to Boston from California, after eight years away, when she finds her scumbag boyfriend cheating on her! When she gets back home she has what feels like the whole world on her shoulders. So she has a ONS. With her older brothers best friend, Niko. The one she crushed on as a kid. Oh but the kicker is he doesn’t recognize her, so she pretends for one night that she isn’t her. And the even bigger kicker... it’s the best sex of her life

This was a hard one for me to rate because it had a lot of elements that I normally steer clear of. The H is a ONS only type of guy. Zero emotional commitment and his ONS reputation and revolving door history with OW is mentioned a lot. The h has a lot of emotional baggage and hang ups, including a cheating ex, lack of self-confidence, and major trust issues.

Maybe it was easy to read without any real struggle because the story keeps a good pace and is always throwing a new twist into t

Cocksure is the book baby of K.I. Lynn and Olivia Kelley, who is a new to me author (not for long though ;)) It couples Niko, a cocky fireman and Everly, the little sister of his best friend and not quite the nerdy little girl who crushed on him, that he remembers.

When Everly decides to flee her life in LA for her hometown, she’s a little nervous over seeing Niko again even if he hasn’t seen her since she was that awkward young girl. So when Niko’s asked to wait for her, drive her home and not l

This book started off as a 3 star read for me but ended as a 5 star. It was a slightly forbidden romance that was a helluva sexy read!

The forbidden aspect is of a best friend's little sister variety. Everly is not the awkward nerdy preteen that Niko remembers. In fact he actually does not recognize her at their first meeting. I was not feeling Niko at all in the beginning of this book. He appeared arrogant, self absorbed and just an overall jerk. He was the definition of a manwhore. When he and
Everyone should want a Niko Callahan to call their own! This was one of the better books I’ve read about a little sister hooking up with their older brother’s friend. Everly (love the name!) fulfills her dream of sleeping with her childhood crush. If only that happens to everyone! Definitely recommend this book. There are happy moments and sad moments but it’s all worth it in the end. And you can’t miss the true (half) Greek god that is Niko Callahan!

Just reading the blurb made me yawn. Read that (or some form of this plot) a few times. And the “I have 9 months to decide what to do” is what I think it is? Even more tedious.
And it seems like most reviews I read agree about some annoying quality of female mc: immaturity.
Please, with a plot like this author still feel the need to worsen it up by adding immature whining female

Mindy Lou's Book Review
I've been wanting to read K.I. Lynn for awhile now. I have a lot of friends who have been raving about her books. When I saw this was up for grabs I knew I had to read it.

As much as I wanted to finally read this author, I was also nervous about that title. I knew that title meant we were getting an arrogant womanizer for a Hero and I'm really not a fan of arrogance.

I was right. In the beginning, that is exactly how Niko came off. He was cocky and a huge player but ultimately, he ended up being

Cocksure is a contemporary romance that is the first book in the series. This book is a standalone romance novel. The Older Brother’s Best Friend read is one of my favorite type of story to sit back and read. This is the forbidden love story of Niko Callahan and Everly Hayes.

Wow! It may have taken me a while to read Cocksure, but it was worth every minute. I loved Everly and Nico! Nico was so hot! Everly used to have a crush on Nico, when she was a kid and followed him and her brother, Cameron around. Now she's all grown up and wants to experience the Nico that really knows his way around a woman's body. She just doesn't want him to know it's his friend's sister, so she lies. When the truth comes out, who will be more upset, Nico, or Everly's brother? I really enjoy ...more

Everly moves back home after catching her boyfriend cheating on her. Being back home after so long brings back memories, such as crushing on her brother's best friend back in the day. Now when she see him for the first time after so long she realizes he doesn't recognize her. So will one wild night with him hurt? I mean if he doesn't remember who she is no harm no foul right? Oh how very wrong she was on that.

I absolutely loved everything about this book! I am a sucker for forbidden romance, especially when that romance involves a best friend's little sister. Cocksure had me giggling, nervous, intrigued, and so many other emotions. I will definitely be reading more from these authors!

Cocksure is the first story I have read from both K I Lynn and Olivia Kelley, but let me just say that it was a fantastic read! This story had it all for me, humour, emotion, chemistry, and a little suspense.

Cocksure drew me in with the title and the synopsis, and while, overall, it is a good read, it lacks that something that made me want to pick it up and ignore the world.

The characters are okay. Nicko is the typical playboy who is never going to settle down until he meets the one. He is persistent in his pursuit, and, surprisingly is the one that wants more. He has many great qualities but his character felt very two dimensional. Everly seems very immature. She runs fro

Niko has been Everly's crush since she was kid. He is her brother's best friend.
When she comes back to Boston, after living several years in California, Niko doesn't recognise her. So, she decides to play a dangerous game. She changes her name in order to spent a hot night with him. He accepts, without knowing that she is Cam's little sister.
That's the beginning of the book. Promising, right?

This was a cute fun read that had me instantly hooked. I have yet to read any books by either of these authors and needless to say, I am a fan. The writing was magnificent, and the story well developed. I am a huge fan of brother's best friend romances, and this one is by far my favorite of the year. Everly and Niko were perfectly crafted, and I loved the fact that Niko fell head over heels for Everly. It was a bittersweet romance.

I hope we continue to see more from this duo as they are amazing
