There are thirteen of these in all, the most powerful and dangerous being Black Thirteen. Rhea of the Coos is jealous of the girl's beauty, and particularly dangerous because she has obtained one of the great glass balls known as the Bends o' the Rainbow. There Roland meets and falls in love with Susan Delgado, who has fallen afoul a witch.

Steven Deschain, Roland's father, sends his son and two friends (Cuthbert Allgood and Alain Johns) to the seacoast barony of Mejis, mostly to place the boy beyond Walter's reach. Roland, however, lays Marten's plans at nines, mostly due to his choice of weapon in his manhood test. We learn of how Marten tried, when Roland was yet a boy, to see him sent west in disgrace, swept from the board of the great game. The Dark Tower is Roland's obsession, his grail, his only reason for living when we meet him. The subtitle of this novel is RESUMPTION. Catching the half-human Walter is for Roland a step on the way to the Dark Tower, where he hopes the quickening destruction of Mid-World and the slow death of the Beams may be halted or even reversed. The first volume, The Gunslinger, tells how Roland Deschain of Gilead pursues and at last catches Walter, the man in black - he who pretended friendship with Roland's father but actually served the Crimson King in far-off End-World. The seventh and last, The Dark Tower, will be published later that same year. Wolves of the Calla is the fifth volume of a longer tale inspired by Robert Browning's narrative poem "Childe Roland to the Dark Tower Came." The sixth, Song of Susannah, will be published in 2004.
