A variation on zombies: a fungus has created the “hungries”. Twenty years after the outbreak, there are very few survivors but this includes some children who have the infection but retain brain function, especially the ability to learn. Not surprisingly, these children are the subject of intensive scientific investigations in a secret army location. The best aspect of this book is the treatment of the sociology of an infection. A major part of the book details a journey with a disparate group of distrustful people who have to cooperate. Overall, a very interesting story.
