It's several months after the eruption of the Yellowstone super volcano, and the world is a vastly different place. Six hundred thousand Americans were killed and millions more have been displaced, scattering to the far corners of the world. Many of them went to Alaska or southern California: two vastly different places with vastly different charms, but one very important thing in common. They're both very far away from the smoking hole in the ground which was once Yellowstone National Park. The whole world has changed. Much of it is still covered with poison ash; ash which will be around for at least a generation. Ash which will shorten the lives of everyone, and not just Americans. People halfway around the globe will be forced to breathe microscopic particles of the ash for many years to come. And everyone will ultimately pay a heavy price. Jenn and her "chitlins" settle in the Mojave Desert near Victorville, California. Gwen and Melvyn and Tony and Hannah choose Etlunka Lake east of Anchorage. And each of them will be terrified when they learn their nightmares aren't over. That a secondary eruption is in the making. This, the final chapter of the Yellowstone saga, focuses not on the dead but rather the survivors. And how they cope in a terribly damaged new world.
