I thought the summary sounded promising, but after giving it a try didn't like this book for several reasons, mainly though the characterisation and dialogue. 
 At times the dialogue just wasn't realistic, and the quotes at the beginning of each chapter felt out of place. They just weren't important or decisive enough to warrant this special place. 
 The characterisation though was what really ruined the book for me. It starts out nice. Yeah, there is insta-love, but I was willing to overlook it for the sake of a bad-girl, ass-kicking heroine. Sadly it turned out the book just followed the usual pattern. 
 The men sleep around, enjoying sex, the girl plans to, but can't go through with it because, haven forbid, women apparently can't have casual sex without getting their feelings hurt. 
 Then there is the usual alpha-male stuff. He sleeps around, but at the same time tells his little brother too keep an eye on her to make sure that she doesn't. 
 The whole thing with her half-brother was so over the top, and urgh. 
 So no, sadly it wasn't for me, I just can't stomach the in my opinion, old-fashioned and sexist portrayal of women and men.
