Onyx (GEM Series, #3)

Supporting the team from the background, Onyx rarely goes out in the field. However, when a widespread child exploitation ring is discovered, her particular skill set is needed to get close.

Unfortunately, her boss—a man she's never laid eyes on before—is dead set against her taking the lead. Outvoted, he finds a way to keep her in his sights,  risking his own exposure.

It's only a matter of time before the final truth is revealed, and they're forced to face the past and secure their future.
