Search Worlds Without End

Resurrected on the lush, mysterious banks of Riverworld, along with the rest of humanity, Samuel Langhorne Clemens (a.k.a. Mark Twain) has a dream: to build a riverboat that will rival the most magnificent paddle-wheelers ever navigated on the mighty Mississippi. Then, to steer it up the endless waterway that dominates his new home planet--and at last discover its hidden source.

But before he can carry out his plan, he first must undertake a dangerous voyage to unearth a fallen meteor. This mission would require striking an uneasy alliance with the bloodthirsty Viking Erik Bloodaxe, treacherous King John of England, legendary French swordsman Cyrano de Bergerac, Greek adventurer Odysseus, and the infamous Nazi Hermann Göring. All for the purpose of storming the ominous stone tower at the mouth of the river, where the all-powerful overseers of Riverworld--and their secrets--lie in wait...

The answers behind the enigmatic origins of Riverworld lie at last within reach, as the remarkable gathering of Earthlings--including Sir Richard Francis Burton, Samuel Clemens, Alice Liddell Hargreaves (the real-life Alice in Wonderland), Cyrano de Bergerac, Ulysses S. Grant, and Baron Von Richtoven--finally breaches the stronghold of Riverworld's extraordinary super-race.

But answers would lead to more enigmatic questions...

Who is the Mysterious Stranger who taunted the Riverworld resurrectees with hints of the truth? What is the key to the gargantuan computer that wields the power of life and death? The astonishing secrets lie within the Dark Tower--but only for those brave enough to seek them and wise enough to decipher them...

Thirty-five billion people from throughout Earth's history were resurrected along the great and winding waterways of Riverworld. Most began life anew--accepting without question the sustenance provided by their mysterious benefactors. But a rebellious handful burned to confront the unseen masters who controlled their fate--and these few launched an invasion that would ultimately yield the mind-boggling truth.

Now Riverworld's omnipotent leaders have been confronted, and the renegades of Riverworld--led by the intrepid Sir Richard Francis Burton--control the fantastic mechanism that once ruled them. But the most awesome challenge lies ahead. For in the vast corridors and secret rooms of the tower stronghold, an unknown enemy watches and waits to usurp the usurpers...
