'the ordinary laws of Nature are suspended. The various checks with influence the struggle for existence in the world at large are all neutralized or altered. Creatures survive which would otherwise disappear.' Headed by the larger than life figure of Professor Challenger, a scientific expedition sets out to explore a plateau in South America that remains frozen in time from the days when dinosaurs roamed the Earth. Seemingly impossible to penetrate, this lost word holds great danger for the four men, whether from fiendish ape-men or terrifying prehistoric creatures. Arthur Conan Doyle's classic tale of adventure and discovery still excites the reader today, just as dinosaurs continue to grip the popular imagination.
