Eternity Road

The Roadmakers left only ruins behind - but what magnificent ruins!
Their concrete highways still cross the continent. Their shattered towers still gleam on the banks of the Mississippi. Their cups and combs and jewelry are found in every Illyrian home. The lost race left behind a legend, as well - a hidden sanctuary called Haven, where a few Roadmakers hid from the mysterious Plague that destroyed their world, and where even now the secrets of their civilization might still be found.
Chaka's brother was one of those who sought to find Haven and never returned. But now Chaka has inherited a rare Roadmaker artifact - a book called A Connecticut Yankee in King Arthur's Court - which has inspired her to follow in his footsteps. A red-haired young woman with a hunter's eyes, Chaka gathers an unlikely band including an aging scholar, an amateur soldier, and a mystic healer. With a reluctant leather-clad frontiersman as a guide, they set out to follow the collapsed roadways north toward the dragon-haunted ruins of Chicago and the thundering cataract Nyagra.
On their journey they will encounter blood-thirsty river pirates, electronic ghosts still mourning their lost civilization, and machines that skim over the ground and even into the air. And they will learn the truth about their own mysterious past.
