She is consumed by a book filled with spells that arrives mysteriously in the mail. The spells share one common ingredient: blood, and Silla is more than willing to cast a few. What's a little spilled blood if she can uncover the truth? And then there's Nick—the new guy at school who makes her pulse race. He has a few secrets of his own and is all too familiar with the lure of blood magic. Drawn together by a combination of fate and chemistry, Silla and Nick must find out who else in their small Missouri town knows their secret and will do anything to take the book and magic from Silla.
