Mahars of Pellucidar

When scientist Chris West saw the video-screen image of a beautiful woman about to suffer a gruesome death in an unknown land, he didn't hesitate to race to her aid by means of an experimental matter transmitter. Plunged headlong into a world of savage men and prehistoric beasts at the Earth's core, the young ex-Marine would soon be fighting for his own life as a captive of the Mahars, cruel reptilian rulers of the inner world of Pellucidar. Also includes the bonus classic novelette Tarzan and the Land That Time Forgot by Joe R. Lansdale!
