In a world where monsters wear human faces, Sera Nightingale is a haunted nurse by day and a ruthless werewolf hunter by night. For five years, she's lived in the shadows, driven by one goal: revenge against the creatures who slaughtered her family. But when a dying wolf shifter lands in her ER muttering warnings of a coming war, everything Sera thought she knew unravels. Then comes Matt Blackwood brooding, lethal, and not quite human. He claims to be a beta of a noble pack and her only ally against the rogue wolves rising under a bloodthirsty warlord named Viktor Bloodbane. But Matt also claims something far more dangerous: that Sera is his fated mate. As Sera is dragged into a secret world of shifter politics, pack rivalries, and supernatural bloodlines, a terrifying truth emerges her very blood holds the key to either ending the pack wars or fueling them. Torn between a past soaked in vengeance and a bond she never asked for, Sera must decide: can she trust the wolf who might be her destiny? Or is he just the next predator waiting for the perfect moment to strike? Enemies to lovers. Second chance. Secret baby. Fated mates. A high-stakes paranormal war is brewing, and Sera is at the center of it all. But when love and loyalty collide, and old wounds bleed anew will she become the savior of both worlds... or the ultimate weapon to destroy them? Is the monster she's been hunting all along the one hiding in her own heart?
