The second book in the Pellucidar series continues from where the first one ended. David Innes has found some help in getting the Iron Mole ready for a return trip. He stocks it with books and other equipment to help the primitive inhabitants break free of the Mahars.
David returns and finds that things aren’t going good for his empire. Old Hooja the Sly One has done a good job of stirring up dissent among the tribes. He has managed to gather the various malcontents into an army which he hopes to make himself emperor. To make matters worse Hooja has kidnapped David’s mate Dian. Now David must rescue his mate, reunite his followers and defeat Hooja and the Mahars.
Another solid entry in the Pellucidar series. The threads left hanging in the first book are resolved and a very satisfying happy ending. The next books in this series are probably some of the finest examples in Burrough’s writing.
