"What’s a pretty girl like you doing out here all alone?"

Hanna’s always been told to fear the Red Moons, an outlier werewolf pack and biker gang. Her pack’s rules are simple: stay in town, stay with your pack, stay safe. Hanna certainly doesn't want to break any rules, not when her pack has already socially shunned her for being rejected by her mate. But when her car breaks down in Red Moons' territory, the biker pack's alpha, Dean Winston, believes she’s a spy and holds her for ransom. But at least they haven't killed her. Yet.

When Dean smells Hanna's scent mixed with his rival's, Joseph Armstrong, the man who rejected Hanna as his mate, Dean’s suspicions are confirmed that she’s a spy. But Hanna hasn’t been around the man who rejected her in months, nor is she a spy. With the clock running out to convince Dean of the truth, Hanna must contend with her heart racing in the presence of the enigmatic and grumpy alpha. Everyone knows werewolves can’t have more than one mate, so why is Hanna drawn to the very man she should be running away from?

When the two of them uncover secrets that her pack has been hiding for decades, they must decide whether to allow things to continue as they've always been, with the two packs simmering in hostility, or to acknowledge that love can even rewrite the laws of fate itself.
