This was my favorite book of the series thus far, because it really had all of the elements I look for in a book. There was a plot, although in the beginning I had some trouble following the scheme that Hailey and friends came up with to trap Cole in the "game" she was playing with him. It all became clear later in the book. I liked that Hailey had a long history with Kyle, dating back to childhood when he used to tease her and play pranks on her. I liked how ruthless Kyle and Cole were in pursuing her.
I really enjoy Jenny Penn's writing, and I love/hate that her male characters lack tenderness and don't ever seem to give in. Of the three books, I think Kyle and Cole were my favorite characters. Cole was dynamic and was able to get through some obstacles. Hailey, especially, seemed to have a had time believing these men were really into her.
Hailey was a great character though, I really loved one scene where she was standing with Cole in her garage, before they became intimate, and just whipped her robe off. He said something like "Girl, you have no shame!" Gotta love a girl with brass ones :)
