Light: The Gone Series

It's been over a year since all the adults disappeared.
Gone.
countless battles have been fought by the kids of the FAYZ: battles against hunger and lies and plague and fear, and of good against evil. But now their worst enemy, the Gaiaphage, has been reborn as Diana's malicious mutant daughter, Gaia. Gaia is endlessly hungry for destruction, and she yearns to conquer her nemesis, Little Pete, then bend the entire world to her warped will. As humanity in the fayz is tested—perhaps for the last time—long-standing enemies become allies, secrets are revealed, and unexpected sacrifices are made. Will attempts to save themselves and one another matter in the end, or will the kids of Perdido Beach perish in this final power struggle?
Light, the sixth and final book in the New York Times bestselling Gone series by Michael Grant, creates a masterful, arresting conclusion to this epic saga.

“As a series finale, this book is more than satisfying—it is epic.” — Voice of Youth Advocates (VOYA) (starred review)
“The Gone books have been one of the most dependable YA series in recent history. Readers dying for this series ender will be rewarded by Grant’s characteristic nonstop action. He keeps readers where he’s always had them—on the edge of their seats—until the very end.” — ALA Booklist
