Book I of Riverworld. Riverworld - huge and mysterious. It has a central river, rimmed by mountains, with a hidden source and and unknown end. Every last soul who ever lived on Earth - from prehistoric apemen to moon-dwelling future civilisations - is reborn there. AS is Si Richard Francis Burton - translator of The Arabian Nights, explorer, brawler, scholar, womaniser, adventurer. His quest is to discover the end of the river, the meaning of the world's existence - and lovely Alice Hargreaves (the real life model for Alice In Wonderland) and he must succeed - for there is an evil experiment being conducted by those who created Riverworld and he must stop that experiment.
