Eighteen-year-old Scarlett is convinced that her vivid dreams are not real, until she starts living through the eyes of Violetta Blackwell. In her dreams, she encounters a mysterious stranger with beaming red eyes and blood-laced claws, the same man who saved her life at her high school graduation camping party: Ember Griffin. But how could a dream alter her entire existence? Scarlett soon discovers that she is a rare soul splinter, and Ember, her soulmate, is still alive three and a half centuries later.

Her connection with Ember grows stronger, but with it comes the risk of losing herself entirely. Can Scarlett survive the vengeance of Violetta and find a way to control her abilities? And will Ember overcome his troubled past to embrace his feelings for her or will he manipulate her memories and force Violetta to the surface?
