Brooks wrote the very excellent World War Z (skip the 2013 Brad Pitt movie). In this new book, Greenloop is a high-tech enclave that is completely isolated by a Mount Rainier volcanic eruption. What follows is a survivalist story that is complicated enormously by an attacking Sasquatch/Bigfoot tribe. The horror of discovering this predatory danger is revealed slowly but inexorably, Stephen King-like. Some of the survival instincts reminded me of Lord of the Flies. Be warned: there is graphic bloody violence. Overall a compelling story, a nice companion to The Centaur’s Wife.
