Used book – The Dark Tower, Volume IV: Wizard and Glass, Stephen King

The Tower is the ultimate goal of the quest for Roland the Gunslinger and his companions: Eddie the Junkie, Susannah the Lady of Shadows, Jake the Martyr Child, and Oy, his favorite animal. All united in a hellish epic where the most terrifying trials are inflicted upon them. They must escape Blaine the Mono, the diabolical railway machine, cross the Dogan Falls, delve into the Kansas plains decimated by a mysterious plague, and once again confront their lifelong enemies.
