Hannah Miller only wants one thing this summer: to lose her virginity before she heads off to grad school. But without any prospects, she assumes her goal will go unfulfilled. But then she goes to stay with her brother Jordan, a first baseman for the Dallas Longhorns, only to find that his best friend Christian is staying with him. Christian, who is sexy and confident and who's been the subject of Hannah's fantasies for years. One look at Christian, and Hannah knows she wants him to be her first. To teach her how to be good in bed.

Newly traded to the Longhorns after a scandal, Christian is looking to start fresh and keep a low profile. But when his best friend's little sister-shy, sweet, slightly nerdy Hannah-propositions him, he can't bring himself to say no. He knows he shouldn't sleep with her, but Hannah is a temptation he can't resist, especially given that he's in the worst slump of his career and could use a boost-what the guys in the clubhouse refer to as a slumpbuster.

What starts out as a temporary summer fling quickly morphs into something more, and before long, Christian doesn't just want to be Hannah's first-he wants to be her last. But when Jordan finds out about their secret hook-ups, all bets are off.
