When a vampire named y/n is discovered near Blackthorn Pack territory, the werewolves immediately demand her death. Only one person stands in their way: Kieran Voss, the loud and fiercely loyal future alpha. Claiming they need answers before spilling blood, he convinces the pack to spare her life and takes responsibility for watching her himself. As Kieran grows closer to the mysterious vampire, old prejudices begin to blur into something far more dangerous. But while y/n learns to trust the werewolf who saved her, Kieran is hiding secrets of his own. Meanwhile, Seraphina Vale—the possessive future luna who has loved Kieran for years—will do anything to drive y/n out of the pack before she steals the future Seraphina believes should have been hers.
