From the Flap:

In the first book of this brilliant series, Stephen King introduces readers to one of his most enigmatic heroes, Roland of Gilead, The Last Gunslinger. He is a haunting figure, a loner on a spellbinding journey into good and evil. In his desolate world, which frighteningly mirrors our own, Roland pursues The Man in Black, encounters an alluring woman named Alice, and begins a friendship with the Kid from Earth called Jake. Both grippingly realistic and eerily dreamlike, The Gunslinger leaves readers eagerly awaiting the next chapter.
