Backstabber (Past Shadows, Book One)

Lena Sione's life hasn't been easy, and she hopes that her cross-country move will settle things down. It does, at least until she catches the eye of Jason Vetra, a junior at her new school. The town rumor is that his quiet, considerate nature is just a front, like the medical research company that maintains his family's fortune. If only that were the end of it.
