In the heart of 1880s Victorian England, Charlotte, a vampire of noble lineage, has always been taught that werewolves are her mortal enemies. Her life is one of elegance and darkness, bound by the strict rules of her kind. But when she encounters Leo, a fierce and enigmatic werewolf, everything she knows is thrown into chaos. Leo, too, has been raised to despise vampires, yet he finds himself inexplicably drawn to Charlotte. As the blood moon approaches, a time of heightened power and ancient prophecies, their worlds collide in ways neither could have imagined.
