Falling Head over Heart — Jennifer Geoghan

Falling Head over Heart: Book Four in the Falling Series
Summer may be over for Sara, but her return to New Paltz University hasn't been a smooth one. In the aftermath of the horrific events of the past few months, Sara finally feels as if she she's come to grips with her new reality. But just when it seems she can finally find a way to live with the memories of her attack, the most unexpected thing in the world happens, something that rocks her world to its very core and forces Sara to flee all she's ever known.
With both Ben and Daniel chasing after her, these two rivals become unlikely allies as they help Sara confront her demons and the growing problem she has a limited amount of time to decide how to handle.
Facing a future she never wanted, who will Sara choose? Daniel, the vampire who ironically is the safe choice? Or Ben, the risk, her best friend, and the man who's given her the most unlikely gift of all.
