David Innes, a wealthy young man, funds an experimental drilling machine and travels deep below the Earth's surface. He discovers Pellucidar, a prehistoric world lit by a central sun, where humans live in fear of giant reptiles and primitive tribes. The adventure is fast and imaginative. Its clear, action-driven prose and short chapters make it a good choice for intermediate English learners who enjoy science fiction.
