Fablehaven 5: Keys to the Demon Prison
Brandon Mull

In this book, Seth and Kendra are put on a mission to find the Translocator, the last of the five artifacts preventing the opening of Zzyzx, the demon prison. Its the last artifact preventing the end of the world. While there, a surprise attack rushes them to get the artifact. Because of this Seth and two others were captured. Unfortunately, when a rescue was attempted, everyone else was captured. Seth escapes though. He goes on a journey to find a magical sword of incredible power. Meanwhile, Kendra escapes with help from the Sphinx. They travel to the island the demon prison was located on. When the prison is opened, all the fairies move out of their lair to create a new prison for the demons. When this happens, the world is saved and everything goes back to normal. This book is amazing and probably the best book in the series. I reccomend this book to everyone.
