A captivating zoological, mathematical, technological, grammatical, architectural, aeronautical literary thriller – unlike anything you’ve read before. When Edvard Tøssentern, the missing author of studies of the mysterious flesh-eating weaver fish, staggers in from a remote swamp, his colleagues at the research station on the island of Ferendes are overjoyed. But Edvard’s discovery about a rare giant bird throws them all into the path of a dangerous international crime ring.

Part-thriller, part-literary and mathematical puzzle, this unique, bold and playful debut engages the reader in an exhilarating game, challenging everything we know – or think we know – about language, morality and truth.
