FBI profiler Zadie Monroe infiltrates Chicago’s most dangerous moon-running syndicate to find her missing sister. The pack’s ruthless enforcer, Callum Rhodes, spots her scent immediately—but instead of exposing her, he offers his protection. Between neon-drenched rooftop chases, speakeasy rituals, and double-crossed clans, Zadie learns Callum’s brutal façade hides a vow to keep his city safe. Falling for him means betraying her badge, yet the only way to survive the coming turf war is to trust the wolf with the sharpest bite.
