Val has a job to do, and it's not what one might expect from Mattsfield High's newest student. She's a Valkyrie and her job is to claim her first soul. That proves difficult in between math exams and history lectures, especially when she starts to fall for her mark, William Johnson, the best swimmer on the swim team. When she lingers, her childhood crush, and loyal bodyguard, Tyler, reminds her of the first rule as a Valkyrie: Don't Fall in Love. Because if she does, Ragnarok is on the horizon, and she only has her heart to blame.
