Devolution: A Firsthand Account of the Rainier Sasquatch Massacre is a fiction book by American author Max Brooks set in the Pacific Northwest.

The narrative follows Kate's journal entries and interviews with Frank and National Park Service ranger Josephine Schell, interspersed with research on Bigfoot and news reports prior to and after the Mt.

The journal entries begin as Kate and her husband Dan arrive in Greenloop, a small ecocentric community that is the brainchild of technology mogul Tony Durant.

Powered by solar panels and biofuel generators, Greenloop is designed to be the perfect community for the Green Revolution; it is removed from crowded cities yet still connected to modern conveniences.

The residents depend completely on drone deliveries for food and supplies, and the only means of receiving wi-fi or a cellular signal is a single fiber-optic cable.

As Kate settles into the community, she describes her troubled relationship with Dan and the other residents of Greenloop; the retired Vincent and Bobbi Boothe, author and professor Alex Reinhardt, psychologists Carmen and Effie Perkins-Foster, their daughter Palomino, and artist Mostar.

As the Washington National Guard and local officials try to regain control of the crisis, tensions in Greenloop grow worse as the town's food supplies dwindle.

However, one night all the residents are awoken by several massive, ape-like creatures tearing open the town's compost bins and agree that they are dealing with a group of Bigfoots.

The true terror for a post-pandemic reader, however, is in the grounded reality of how victims of disaster can be overlooked and how thin the veneer of civility and technology is revealed to be in the face of grand social disruption.

[6] Publishers Weekly and Library Journal also had positive reviews, saying Brooks "packs his plot with action, information, and atmosphere, and captures both the foibles and the heroism of his characters",[7] and that it was a "creative and well-executed conceit" that would also appeal to "those who appreciate nonfiction survival stories".

"[10] American gun enthusiast and self-defense instructor Massad Ayoob reviewed the book, concluding that it presented a good case for firearms ownership.
