' lives up to its magnificent billing' A tale of exciting scientific discovery, tells the story of Samuel Turvey's expeditions to the island of Sumba in eastern Indonesia. While there, he discovers an entire recently extinct mammal fauna from the island's fossil record, revealing how islands support some of the world's most remarkable biodiversity, and why many of these unique endemic species are threatened with extinction or have already been lost. But as the story unfolds, an unexpected narrative emerges – Sumba's Indigenous communities tell of a mysterious wildman called the 'mili mongga', a giant yeti-like beast that supposedly lives in the island's remote forests. What is behind the stories of the mili mongga? Is there a link between this enigmatic entity and the fossils that Sam is looking for? And what did he discover when he finally found the tomb of a mili mongga? Combining evolution, anthropology, travel writing and cryptozoology, explores the relationship between biodiversity and culture, what reality means from different cultural perspectives, and how folklore, fossils and conservation can be linked together in surprising ways.
