As conditions worsen in the FAYZ, where supernatural forces have trapped children under the age of fifteen and resources are running out, it becomes tempting to heed the words of a prophet who says that only death will set them free.

A deadly, flu-like epidemic and a plague of flesh-eating creatures threaten the lives of the children at Perdido Beach while Sam, Astrid, Caine, and Diana each struggle with doubts and uncertainties.

"Answers to every mystery of the FAYZ are revealed, unexpected heroes emerge as sacrifices are made, and the Darkness is finally conquered by a force even more powerful than itself in this conclusion to the Gone series"-- Provided by publisher.
