Professor George Edward Challenger is now a resident of the Dreamlands, that realm envisioned by fantasy writer H.P. Lovecraft, and he does not know whether he is dead or alive. He does know, however, that a sedentary life is not for him, so the Edwardian adventurer goes on a grand expedition to find the hidden sources of the River Skai, a river greater than the Nile and far more mysterious.
