Synopsis

David, Christopher, April and Jalil accomplished what they set out to do in Egypt: they found Senna's mother, and can only hope she provides the Coo-Hatch with a passage back to their own world. But now Neptune, ruler of the sea, is intent on getting the intruders off his ocean, and down into his world. On the bottom of the sea, David and the others find the lost city of Atlantis, a place where most creatures go and never, ever return. The tenth Everworld book, narrated by David.
