Forest Glen, Pennsylvania. A peaceful suburban neighborhood where nothing unusual ever happened – until the day Masaman the Troll moved out from under his bridge and bought the old fixer-upper on Oak Tree Lane.

Now goblins swarm the neighbor's front porch and kitchen windowsill in search of freshly baked pies and cookies; a cat-food eating zombie canvasses the residents, looking for landscaping and interior decorating opportunities; and a dwarf takes time out from Poker Night to investigate the rash of burglaries that suddenly plague the neighborhood.

And the Neighborhood Watch has no idea who it should be watching.
