Maia Whitney has held men as they died before, but never in peacetime, and never in her aunt's front hall. And this unexpected death is only the beginning. Someone is stealing magic and life from England's magicians and using them for his or her own gain. No one is safe, not even Magical Intelligence Agent Lennox Davies, whose targeting by the parasite brings him his own set of challenges to work through. Though she is only an apprentice, Maia will not sit back and wait for others to bring about justice, and teams up with Len as she did once before. Using a blend of magical skills and detective work, together Maia and Len dig deep into a case that has its roots buried in the shadows of the past ... and could leave one of them magic-less forever.
