When American anthropology graduate Maya Chen travels to Buenos Aires to study the viral Therian phenomenon—teens wearing animal masks, running on all fours, howling at the moon on TikTok—she expects rebellious youth seeking internet fame. What she finds instead is a hidden world of real shifters, descendants of an ancient wolf bloodline living undetected in the heart of the city. And the terrifying, magnetic Alpha who leads them doesn't just see her as a researcher—he sees her as a threat. Until the full moon reveals the impossible: Maya carries the dormant blood of the Lost Wolf Queen. She is his fated mate. Now caught between two worlds, Maya must survive pack politics, a rival Alpha who wants her power, and the undeniable pull of a mate bond that could destroy everything she's ever known.
