Ander Forrest renounced blood magic to become a nurse-healer in his rural hometown, far from the drama of wizardry and espionage his sister Kate craved. When Kate goes missing in action, Ander finds himself the legal guardian of her gifted twins and receives a cryptic warning from Kate's husband to protect them before he, too, disappears.

Six months later, his former lover crash lands in the kids' bedroom via a spell only Ander's sister could have cast. Druid Cai Piper doesn't remember how he got there, but he knows he never stopped loving Ander, and that he was sent to protect him and the twins. Cai is strangely drawn to Forrest House and the land it stands upon.

With the secrets of a clandestine wizards' order hanging between them, Cai and Ander must remember how to trust each other as sinister forces move against the Forrest family—magical terrorists who want to exploit their rare sorcery and bring the world to its knees.
