This companion book to The Forest of Hands and Teeth has some recurring characters and is very similar in tone to the first book. This story is also gruesome and dark, full of disturbing imagery and graphic violence. The Mudo, (called the Unconsecrated in the first book) or zombies, are moaning, haunting characters whose only need is to infect others, and who can only be stopped by decapitation. Violent fighting and death are prevalent. Kissing occurs, and a true love story from the previous book shows up again in this one. This book also highlights a powerful female role model, one who is courageous, strong and who perseveres even in the face of great adversity. A nice message is conveyed about learning to push the boundaries or barriers that surround us.
