I
First published in 1982

As the world moved on he followed, for a nameles time.  Naked between the unforgiving sun and the sterile sand, blind in the bowels of the mountains where no light penetrates, shadowed by dangers both magic and physical, the gunslinger moved steadily oh his destined path.
For beyond the hazards of the way - the crazed seer, the speaking demon, the slow mutants, the undead boy, and yet stranger sorceries - he would hear, on the night that was ten years long, of the Dark Tower.  Nexus of Time and Space, the tower where he would one day come, winding his horn for some unimaginable final battle....

The start of an incredible series of books.  Great story.
