So when he meets his sister's roommate during a visit to the university, the flirting starts completely naturally. As much as Cassie is drawn in by Tyler's twinkling eyes and dimpled smile, she's aware that he has a bit of a reputation and is widely known to be afraid of commitment. She's not willing to make herself vulnerable to someone who could so easily break her heart. Despite Cassie's attempts to distance herself from Tyler, it seems the fates have conspired to constantly throw them into each other's paths. As Cassie fights her attraction, not wanting to ruin her relationship with Tyler's sister, the closest thing Cassie has to family, Tyler comes to the terrifying realization that he just might be in danger of losing his most sacred possession: his heart.
