Flung to an alien ocean world, John Bandicut and his companions find themselves plunged into the deepsea realm of the Neri. What will they find in the Neri's failing undersea city, or in the terrifying object of the deep abyss? Book 3 of The Chaos Chronicles continues the hard-SF saga inspired by chaos theory—with an all-new Afterword by the Nebula-nominated author of Eternity's End.
