Something is wrong with Nora. There’s a darkness inside her that she can’t seem to control. As she and her men search for answers to her siren’s dark nature, someone puts out a hit on her clan. Now, mercenaries from all over are trying to kill them. On top of all that, Nora must take on her first official case for the FUA. Someone is stealing mythical creatures, and they need to be stopped before they can steal the magic of the world’s most powerful underworlders.

This is the 4th and final book in the Nora Jacobs series.
