For sixteen years, Y/N lived a normal life. No vampires. No prophecies. No destiny. At least, that's what she thought. When a series of terrifying visions begin haunting her dreams and vampires start hunting her across Sunnydale, Y/N discovers a truth that was buried long before she was born. She is the Lost Slayer. A girl erased from the Watchers Council records because of an ancient prophecy. A prophecy that foretells the rise of a Slayer powerful enough to split the Slayer line itself. Now Buffy Summers and the Scooby Gang must decide whether Y/N is their greatest ally... or the beginning of the next apocalypse. And as dark secrets emerge, Y/N finds herself drawn to the last person she should trust: Spike. The vampire who seems to know more about her destiny than anyone else.
