Roadmarks;

"A mindbender of a book, and a treat for Zelazny fans."
ALA BOOKLIST
The Road runs from the unimaginable past to the far future, and those who travel it have access to the turnoffs leading to all times and places--even to the alternate time-streams of histories that never happened. Why the Dragons of Bel'kwinith made the Road--or who they are--no one knows. But the Road has always been there and for those who know how to find it, it always will be!
