In the rain, surrounded by unconscious attackers, she opens the envelope in her pocket. It says her name is Myfanwy Thomas. It says, "The body you are wearing used to be mine."

The new woman in the body of Myfanwy Thomas discovers she is a high-ranking official in a secret organization protecting the UK from supernatural threats. With only the research of a complete stranger—herself—and instinct to guide her, she must find the traitor in its ranks—the operative who erased the original Myfanwy.

This book is suspenseful, kind of creepy, and extremely funny. Plus, it's got some top-notch world-building. I would love to read a sequel!
