Death Planet — Ruth Ann Nordin

The soil is dying and the air is losing its oxygen. The devastation begins at the equator but is quickly spreading north and south. Soon the entire Earth will become uninhabitable to everyone and everything living on it. As the scientists hurry to find a solution that will be mankind's salvation, Adam Riley works on a time machine. Adam succeeds in building his machine, and he travels in the past to find a solution, but the answer is not in the past. By accident, he finds himself in the future where people have long since been extinct. The new species, the Erudites, decide to bring humans to their time so mankind may continue to live. But Adam's sister leads a rebellion that will lead Adam to the discovery of what caused mankind's extinction. Through this discovery, Adam will be forced to make a choice that will determine the fate of both mankind and the Erudites.
