Another installment full of shocking reveals as this group of teenagers from Idaho accept their fate as the last humans on Earth and attempt to make do with the stockpile of supplies they have remaining while trying to keep the peace with the various tribes that have split up during the first few months out of the program and back in their real bodies. The first problem to arise? Their silo full of supplies is threatened by a landslide and then a flood from the nearby lake which proves especially dangerous given the fact that one of the girls is suspicious that it is sabotage, not nature, that is trying to kill off the group.

The story quickly escalates as more unthinkable truths are revealed and Min and Noah have to separately tackle one obstacle after another to protect their friends and keep humanity alive. I'm saddened that this might be the last book spent with these characters and this absolutely insane end-of-world scenario, but Reichs has proved to be an adept storyteller so I'll likely read whatever he comes out with in the future.
