What would you do if everything you were taught about your home planet was a lie? What would you do if you were Left Behind? ENDIRION is a thirteen year old boy like any other. Except his skin is green and it glows. And he doesn't have any hair on his head or anywhere else on his body. Oh and he lives in a cave underground. But so does everyone on the poisoned Mother Planet. There is little to eat and what they do have is as mutated as the people themselves. Fuel is scarce and technology exists only in history books. Or so they are told. When Endirion and his classmate Harlo are sentenced to hard labor at the Dump they see things that go against everything they have ever known about their planet. Determined to find out the truth the boys set off on a dangerous journey that pits them against angry marshals, mysterious animals, mutant humanoids, and lands them in the belly of a Monstruwhale. It is a harrowing quest that takes them down remote tunnels, across the Lake of Fire, into the Madlands and a whole new world.
