The debt wasn't hers, but she’s the one paying it. When Sera Caldwell’s boyfriend vanishes, he leaves behind a mountain of gambling debts and a signed contract that leaves Sera holding the bag. In a world where the law of the pack is the only law that matters, Sera is seized by the pack who made the loan and handed over to their alchemist as a human test subject. She isn't just a prisoner; she’s an experiment. Dosed with a volatile serum designed to induce a chemical heat, Sera is forced into a state of biological receptivity she never asked for. Her "tester" is Kael, a lethal enforcer who has been ordered to document her reaction-and her receptiveness. Kael is a predator who follows orders, and his current order is to see just how far the serum can break her. But the experiment backfires. What was supposed to be a clinical test of breeding behaviors sparks a connection that defies the alchemist’s science. As the drug blurs the lines between forced instinct and genuine desire, an unexpected and fierce bond begins to take root—one that Kael will kill to protect and Sera will fight to claim as her own.

Alpha Test is the first book in the Primal x Prey series. It is a gritty, high-heat dystopian romance featuring heavy power imbalances, forced proximity, and an unexpected, unbreakable mate bond.
