About this book

Rhea Morven is a rookie Merlin agent with a cursed bloodline that makes her a walking magical anomaly and an outsider to those around her. On her first day, she is assigned to Gallows Gate, a hidden town concealing secrets and supernatural creatures, to locate three missing paranormals before the community destabilizes. The missing individuals are the children of the town's ruling council, complicating her investigation. Rhea must navigate vampire politics, witch rivalries, and council members skeptical of her success. She relies on her sharp wit and dangerous magical abilities to navigate the case. A shifter with gold eyes repeatedly intervenes to save her life, creating a distraction from her work. Rhea was sent to fail, but she is determined to complete the assignment. The series centers on found-family dynamics, magical suspense, and snarky characters.
