title: The Amethyst Tower
author: Wiesner, Karen
description: For the ten generations since the evil first came to Woodcutter's Grim, the Guardians have sworn an oath to protect the town from the childhood horrors that lurk in the black woods. Without them, the town would be defenseless…and the terrors would escape to the world at large.
  
  Loosely based on Rapunzel. The isolated maiden meets her knight in a time-traveler who's come into the future to rescue her from the Warlock Lord holding her captive in the amethyst tower. Where else but in the fairy-tale-horror town of Woodcutter's Grim?
