Leo's Map of Monsters: The Frightmare

It's Leo's job as the Guardian's apprentice to protect the village from the monsters that lurk in the surrounding forest. Whenever a monster gets too close to the village walls Leo must venture out, using his magical map to first find the monster and then do battle with it. In this book, Leo must track down the ghostly Frightmare-a powerful monster that haunts the abandoned ruins, breathing deadly blue fire at any intruder.
