The team of explorers from The Lost World reunites to face the end of the world in this adventure by the creator of Sherlock Holmes.

Prof. George Challenger has made a troubling discovery: The Earth is about to pass through a belt of poisonous gas. He quickly summons his three friends—Professors Summerlee, Lord John Roxton, and Edward Malone—to his home in Sussex with a request to bring tanks of oxygen.
Once the men arrive, Professor Challenger leads them and his wife to a sealed room where they can wait out the crisis and observe the chaos outside. But when the poisonous cloud finally dissipates, there is no telling what they will find . . .
