Adventure calls from the jungle kingdom of South America, and this time Tom Swift stays behind to build the machine that might save it. When King Amo's crown, carved from the same meteorite metal that powers Tom's giant telescope, is stolen by masked raiders, giant servant Koku returns home to lead a rescue expedition, and Ned Newton goes with him. Together they face a hidden lost city, industrial spies from a rival corporation, a sea monster guarding a sunken reef, deep-sea diving into shipwreck ruins, sabotage, kidnapping, and a conspiracy that reaches back to Shopton itself. Packed with invention, mystery, danger, loyalty, and discovery, KOKU'S CROWN is a jungle-and-ocean thrill ride for fans of classic pulp science adventure: meteorites, telescopes, sea monsters, lost kingdoms, spies, and unbreakable friendship, all in one race against time.
