This is the second Jeremy Robert Johnson book I've read. The gist is that nuclear bombs were launched on, at least, the United States. The main character, Dean, survived the blast, seemingly because of his suit. Dean sewed cockroaches all over his suit. General destruction, need for survival, type of thing. Dean forms a bond with the cockroaches and he meets a woman who has formed a similar bond with ants. Each chapter just made me eager to read the next. It's a short read, but good book is good.
