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.
