When 13-year-old Ralph's parents suddenly split up, he's expecting a boring-and depressing-summer. But his conspiracy-theorist neighbor has other plans. Soon Ralph and his spunky best friend Aurora are swept into a zany adventure involving hidden maps, secret identities, ridiculous disguises, grave robbing, suspicious fires, pterodactyl shrieks, a mad-scientist's laboratory, scissor-teeth, a jewelry thief, and F. Scott Fitzgerald.
