Young magic-user Blue de la Cour is sent to live with a powerful woman after Blue's father is murdered. Unfortunately, the only person who can help her is the boy she's hated her whole life, Prince Kellan Renard. Kellen, on the other hand, is learning how to navigate politics and war, and is being forced by his royal family to marry a daughter drawn from some of the most powerful families in the kingdom. The only person who is able to draw his attention away from that pressure is the girl who ruined many of his childhood adventures, Blue. When mysterious disappearances occur throughout the kingdom, Blue and Kellen join together to investigate, then fight against, a growing evil. And as the pressure mounts, and their feelings for each other grow, they must make decisions for the future that could cost them everything.
