A modern fantasy world built on the premise that the gods of every major mythology are real, immortal, and still active in human affairs. The Greek and Roman gods relocated to America when it became the seat of Western civilisation. The Egyptian gods never left the world at all. The Norse gods operate from a network of worlds connected to Scandinavia and beyond. In each case, the children of gods walk among ordinary humans, inheriting powers and problems in equal measure. Beginning with Percy Jackson and the Olympians, Rick Riordan's interconnected series spans five separate story lines covering Greek, Roman, Egyptian, and Norse mythology, with characters crossing between them as the scope expands. What holds it together is less the shared cosmology than the shared sensibility: mythology treated as living history rather than dusty legend, heroes who are funny and frightened and loyal, and a consistent argument that the monsters worth fighting are usually the ones who claim to be on your side.
