Series background & context
Writing under the pen name C. Reilly, this series moves away from romance into sci-fi thriller territory. It follows a secret branch of the FBI that employs agents with "Variations"—genetic anomalies that give them special abilities.
The protagonist, Tessa, must use her unique skills to stop serial killers and solve crimes while navigating the dangers of a government that views her as a tool rather than a person. It combines procedural suspense with supernatural elements.
