The memories her family has tried to bury resurface when Daniel returns, three years later, and enrolls in Grace and Jude's high school. Despite promising Jude she'll stay away,

The closer Grace gets to Daniel, the more she jeopardizes her life, as her actions stir resentment in Jude and drive him to embrace the ancient evil Daniel unleashed that horrific night. Grace must discover the truth behind the boy's dark secret...and the cure that can save the ones she loves. But she may have to lay down the ultimate sacrifice to do it—her soul.
