Mondamin Court is a quiet block in a typical Midwestern city. That is until Rick, Ryan and Kyle return from a Red Cross Mission to the South Seas worshiping the ancient Cult of Dagon. Holly Wheatsfield sees Dagon itself, and begins to go mad. Zoey transfers from the state university to Miskatonic and a distant relative to Dr. Herbert West appears on the block. And nothing will be typical once the action starts.

Mondamin Court is a typical lower middle class neighborhood in a midwestern city. The people are a cross section of normal Americans. Each book starts with the same setting and characters but they face a different apocalyptic scenario.
