Abandoned and scared, but less alone than he could have ever imagined, Sam awakens to the screams of the other children on the island of Fervor, and the absence of all adults. To make matters worse, despite hearing this chaos in his head, he finds himself deaf to the normal sounds around him. His only answers are now being provided by a strangely charismatic boy named Francis who is about to lead Sam to a gathering that will alter his life. Why have things changed so drastically on the island, who is responsible for these changes, and what does this mean to the remaining inhabitants of Fervor?
