When Buenos Aires therapist Dr. Valentina Reyes takes on a teenage client who genuinely believes he is a wolf, she thinks it is just another case of the Therians trend sweeping TikTok. But Nahuel is no TikTok poser — his blood carries the dormant genes of the last wild Lycan pack of Patagonia. And when Valentina touches him during a therapy session, something ancient awakens in her too. She is human. He is seventeen and convinced he is a wolf. And the terrifying, impossibly attractive man who shows up claiming to be Nahuel Alpha says Valentina is his Mate — the one his wolf has been searching for across three centuries. In a world where the Therians craze has exposed long-hidden shifter communities, Valentina must untangle clinical psychology from supernatural bond, fight a rival Alpha who wants Nahuel power, and decide whether the heat in her veins is madness — or the most dangerous love she will ever know.
