Night of the Living Rerun (Buffy the Vampire Slayer, Book 4)
A history Lesson? As long as there have been vampires, there has been the Slayer. One girl in all the world, to find them where they gather and to stop the spread of their evil and the swell of their numbers. As if real life wasn't already overflowing with vampire-staking, now Buffy has begun to dream about slaying! Night after night, it's the same thing. She's back with the Puritans, a Slayer on the trail of a witch. What can it mean? Buffy gets a clue when Xander and Giles start acting like they have ancient alter egos. Now the stage is set for a symbolic replay of the night the Master was accidentally trapped in the other dimension. Only this time, the Master wants a happy ending -- for himself. Buffy and her friends must prevent the Master from rewriting the script and escaping his supernatural prison before Sunnydale becomes history!
