At the Earth's Core, Paperback

Beneath the earth's surface lies a world of eternal daylight - Pellucidar. Scattered throughout are communities of distrustful humans and the cities of the reptilian, highly evolved Mahars. The authors' discovery of Pellucidar and the struggle to unite the human communities and overthrow the Mahars is a tale of conquest, deceit, and wonder.
