At Spiral Hall, an invitation-only school for the world's top ecodemics, eleven-year-old Peter Blue is something of a legend, or so he's told. His father, a top agent at GAIA - the Global Advanced Intelligence Agency - has been missing for years, believed dead. But new intelligence determines he might be alive and held captive by sinister handlers who control the Anthrogs - demonic creatures born from garbage dumps that show up as wildfire and killer storms. As Peter gains skills and knowledge to fight these forces, he must prove to himself that he's more than just a legend, to save his father and the world, before it's too late.
