Bobby Pendragon is a seemingly normal fourteen-year-old boy. He has a family, a home, and even Marley, his beloved dog. But there is something very special about Bobby. He is going to save the world. ...Before he can object, he is swept off to an alternate dimension known as Denduron, a territory inhabited by strange beings, ruled by a magical tyrant, and plagued by dangerous revolution.

"When supernatural phenomenon start following Marcus O'Mara around, he discovers a key that leads to The Library, a place where all the stories of the living and dead are kept that will help him and his friends solve a terrifying mystery"--

Having escaped from Pemberwick Island, Kent, Tori, Olivia, and Tucker continue to try to get word out about SYLO, the organization that had quarantined them, while trying to avoid being caught in the middle of an inexplicable new civil war.

Marcus is an agent of the Library, a place filled with tales that don't have an ending. Puzzles that won't be solved until Marcus and his friends step in to finish them. This time it's their own stories at stake. Theo just visited the Oracle Baz, an old amusement-park machine that spits out fortunes for the cost of a quarter. Fun, right? The only problem is, the oracle's cheap predictions have been coming true . . . and Theo's fortune says that life...
