Headed by the larger than life figure of Professor Challenger, a scientific expedition sets out to explore a mysterious plateau in the Amazon rainforest. The adventurers find themselves trapped in a world lost in time, inhabited by dinosaurs and apemen. They too must take part in an ancient struggle for survival... Arthur Conan Doyle's classic tale of adventure and discovery remains as witty and enthralling as when it first appeared in 1912. This new critical edition explores the cultural contexts of one of the most entertaining books ever written.
