The snow pack is four feet deep now and he's not going anywhere anytime soon. But he and Josie are becoming closer and he's okay with that. Inside Salt Mountain four hundred miles to the south Mark and Hannah are anguished. Hannah's convinced not only that Frank is dead, but that she is somehow responsible. Eden South is overrun by brutal men who hold seventy five hostages. Marty's best friend Lenny is the first to fall. But he won't be the only one. And at Joint Base San Antonio, two surgeons who made an error in judgment await court martial and a possible sentence of death.
