Damnation Alley - Roger Zelazny

The world has been devastated by atomic war and only small pockets of civilization still exist in an inferno of deadly storms, tortured volcanic landscapes and monstrously mutated animals. In North America the major surviving centres are California and Boston. And Boston is ravaged by a terrible plague with the only serum in California, three thousand miles of radioactive wasteland away...

Hell Tanner is one of the last of the biker Angels, a survivor of the Big Raid that destroyed America, and the only man with even the ghost of a chance of making the nightmare journey through Damnation Alley.
