The book opens with a 12-year-old girl named Erin having an incredibly vivid and confusing dream. She wakes up and starts her paper route. Because it's November 1, there's a lot of residual Halloween weirdness out on the streets, and soon she finds herself the target of some teenage boys who are wearing costumes while vandalizing the neighborhood. Erin is rescued by several newspaper delivery girls who are traveling together for safety, and then the narrative takes a surreal turn. Some folks in the neighborhood start disappearing, and people who appear to be wearing Halloween costumes seem to be from different times or places. The papergirls try to figure out who is attacking them and why, who are their allies or enemies, and just what on earth is going on.
