Parts 1 & 2 What if, after you die, you are reborn on another planet, along with everyone else who has lived and died on Earth? And what if, in this incredible life after death, there comes death after death, after death, after death? Welcome to Riverworld, a place of strange, watery beauty and the current abode of a fascinating cast of the recently (and not-so-recently) dead. It certainly isn't Heaven, but it just might be Hell. Matt, an American journalist, and his fiancee, Jessie, are killed in an explosion, but reawaken in this unusual afterlife. Everyone who has ever lived on Earth has been resurrected simultaneously in this strange new world. Determined to find Jessie, Matt joins forces with an intrepid crew, including a 13th century female warrior and riverboat captain Mark Twain. As they embark upriver, their adventure begins, all the while tracked by the watchful eye of a mysterious alien force.
