whom Walter foretold; Roland prevents Mort from murdering Jake Chambers, and shortly afterward Mort dies beneath the wheels of the same train which took Odetta's legs in 1959. Roland thus fails to draw the psychotic into Mid-World ... but, he thinks, who would want such a being in any case?
Yet there's a price to be paid for rebellion against a foretold future; isn't there always? Ka, maggot, Roland's old teacher, Cort, might have said; Such is the great wheel, and always turns. Be not in front of it when it does, or you 'II be crushed under it, and so make an end to your stupid brains and useless bags of guts and water.
Roland thinks that perhaps he has drawn three in just Eddie and Odetta, since Odetta is a double personality, yet when Odetta and Detta merge as one in Susannah (thanks in large part to Eddie Dean's love and courage), the gunslinger knows it's not so. He knows something else as well: he is being tormented by thoughts of Jake, the boy who, dying, spoke of other worlds. Half of the gunslinger's mind, in fact, believes there never was a boy. In preventing Jack Mort from pushing Jake in front of the car meant to kill him, Roland has created a temporal paradox which is tearing him apart. And, in our world, it is tearing Jake Chambers apart as well.
The Wastelands, the third volume of the series, begins with this paradox. After killing a gigantic bear named either Mir (by the old people who went in fear of it) or Shardik (by the Great Old Ones who built it... for the bear turns out to be a cyborg), Roland, Eddie, and Susannah backtrack the beast and discover Path of the Beam. There are six of these beams, running between the twelve portals which mark the edges of Mid-World. At the point where the beams cross - at the center of Roland's world, perhaps the center of all worlds - the gunslinger believes that he and his friends will at last find the Dark Tower.
By now Eddie and Susannah are no longer prisoners in Roland's world. In love and well on the way to becoming gunslingers themselves, they are full participants in the quest and follow him willingly along the Path of the Beam.
In a speaking ring not far from the Portal of the Bear, time is mended, paradox is ended, and the real third is at last drawn. Jake reenters Mid-World at the conclusion of a perilous rite where all four - Jake, Eddie, Susannah, and Roland - remember the faces of their fathers and acquit themselves honorably. Not long after, the quartet becomes a quintet, when Jake befriends a billy-bumbler. Bumblers, which look like a combination of badger, raccoon, and dog, have a limited speaking ability. Jake names his new friend Oy.
The way of the pilgrims leads them toward Lud, an urban wasteland where the degenerate survivors of two old factions, the Pubes and the Grays, carry on the vestige of an old conflict. Before reaching the city, they come to a little town called River Crossing, where a few antique residents still remain. They recognize Roland as a remnant of the old days, before the world moved on, and honor him and his companions. After, the old people tell them of a monorail train which may still run from Lud and into the wastelands, along the Path of the Beam and toward the Dark Tower.
Jake is frightened by this news, but not really surprised; before being drawn away from New York, he obtained two books from a bookstore owned by a man with the thought-provoking name of Calvin Tower. One is a book of riddles with the answers torn out. The other, Charlie the Choo-Choo, is a children's book about a train. An amusing little tale, most might say . . . but to Jake, there's something about Charlie that isn't amusing at all. Something frightening. Roland knows something else: in the High Speech of his world, the word char means death.
Aunt Talitha, the matriarch of the River Crossing folk, gives Roland a silver cross to wear, and the travellers go their course. Before reaching Lud, they discover a downed plane from our world - a German fighter from the 1930s. Jammed into the cockpit is the mummified corpse of a giant, almost certainly the half-mythical outlaw David Quick.
While crossing the dilapidated bridge which spans the River Send, Jake and Oy are nearly lost in an
