One night while on patrol, the Slayer and her friends are outnumbered and receive aid from a totally unexpected source:
Buffy's old flame, Pike. He and Buffy had a complex relationship back in Los Angeles, when the Chosen One was first called. Now, Pike has arrived in Sunnydale, on the run from a stone demon with a grudge. Faced with this blast from the past, Buffy finds herself caught between her history with Pike... and her future with Angel.
But there's little time to contemplate this situation as vamp activity rises and Giles, in particular, becomes the target of mysterious, brutal attacks. Buffy suspects a deeper connection between old friends and new enemies. With the help of her friends, Buffy unmasks the evil entities – and discovers that even a Watcher can be watched...
