Debris TPB

"In the far future, humanity has doomed planet Earth to rot and decay, covering her surface with garbage. Now, ancient spirits called the Colossals rise from the debris and attack the remaining survivors, forcing the human race to the brink of extinction. After an attack leaves their people without water, Maya, the last Protector, sets out on a journey for pure water, to save the world before the monsters bring it all to an end."
