My brother was knocking on the bunker door. My brother was also sitting beside me. Eight years after the outbreak, Rowan Hale knows the infected can imitate the living. What she doesn’t know is how the thing outside learned her brother’s voice—or why the man protecting them wants her to open the door. Then she finds the medicine he refused to give her dying brother. Beside it: a transfer list bearing their names. Rowan escapes with her twin brother and her best friend, Tess, only to discover that surviving a bite can make someone worth hunting. Their last hope is Mercy Ridge, a fortified community with doctors, fresh food, and children playing behind its walls. But its medical records tell a different story. Some residents are patients. Some are prisoners. And some are wearing glasses for a reason. To protect the people she loves, Rowan must discover what the city is keeping alive—and what it is willing to take from everyone else.
