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, too. 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. He's sweet, flirty, experienced, and she trusts him. 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, even though he knows Jordan would kill him if he found out what Hannah and Christian were getting up to in the middle of the night. 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.
