Devolution

Greenloop is a small eco-community in the Cascade foothills, built around solar power, high-speed internet and the promise that technology can keep its residents comfortable. When Mount Rainier erupts, those comforts stop mattering. The residents are stranded, and the settlement's connection to the outside world is gone.

The eruption has also driven Sasquatch out of their territory. Displaced and starving, the creatures begin to treat Greenloop as a place to hunt. The residents have no weapons and no preparation, and they face a predator they had no reason to believe existed.

The book is an epistolary horror novel, presented as an investigation into what happened to the community. It is assembled from a recovered journal, interviews, transcripts and other documents, so events reach the reader as testimony and fragments rather than a single narrated account.

It was published in 2020 and comes from Max Brooks, who used a similar documentary format in World War Z. The format lets the book question how poorly a comfortable modern life prepares people for real crisis, and the reader pieces together the fate of Greenloop from the records left behind.
