I'm not sure how I got through the first half of this book. The hero is petty, short-tempered, arrogant and just generally a douche. He hates the guy who stole his captaincy in high school (not at all petty, btw) and plans to seduce his sister to get back at him.
And while some people see cockiness as charming, I never have, so I don't even understand why she fell for him.
I will say though that once he realized he was in love with her and had to confront his douche-ness, he became a lot more likable and I starting enjoying the book more. Overall though, still only mediocre.
