Okay I enjoyed the first book but I LOVED this one! First of all, I'm a sucker for redheads and Grace fulfills that with her beautiful flaming hair and freckles. Then she's a book nerd on top of it who makes an arrangement to work through a list of sexual experiences with Cooper, reformed playboy hockey hottie with dark hair/beard and blue eyes who is also actually a big nerd? I love them both and their relationship. She's his coache's daughter, which he doesn't know the first time they hook up. She wants to take control of her life and move on, almost four years after a high school boyfriend broke her trust and traumatized her, and she decides that if the rumors about Cooper's skills with the ladies are true, he's the perfect candidate. They start as a mutual partnership (he's been having a dry streak and it's affecting his game until they hook up), then evolve to friends with benefits, and then more. It happens so naturally as they fall for each other. He is such a sucker for her and become the ideal book boyfriend. They support each other, nerd out together, make each other laugh, and are very sexually compatible. I'm still looking forward to the other two siblings' books in the series (especially now that I know who Seb's LI is), but I have a feeling this book will remain my fave of the four.
