The Dark Tower III: The Waste Lands

Five weeks after the events of the previous book, Roland, Susannah, and Eddie have moved east from the shore of the Western Sea, and into the woods of Out-World. After an encounter with Shardik, a gigantic cyborg bear, they discover one of the six mystical Beams that hold the world together. The three gunslingers follow the Path of the Beam inland to Mid-World.

Roland now reveals to his ka-tet (group of people bound together by fate/destiny) that his mind has become divided and he is slowly losing his sanity. Roland remembers meeting Jake Chambers in the way station and letting him fall to his death in the mountains[N 1]. However, he also remembers passing through the desert alone and never meeting Jake. When Roland saved Jake from being killed by Jack Mort in 1977[N 2], he inadvertently created a paradox; Jake did not die and thus did not appear in Mid-World and travel with Roland.

In 1977 New York, Jake Chambers is experiencing exactly the same mental divide, which is causing alarm at his private school, and angering Jake's cocaine-abusing father. Roland burns Walter's jawbone and the solution to his dilemma is revealed, but to Eddie instead of Roland. Eddie must carve a key that will open the door to New York in 1977.

Jake abruptly leaves school and finds a key in a littered vacant lot where a single red rose has bloomed. Jake manages to pass into Roland's world using the key to open a door in an abandoned haunted house on Dutch Hill in his place and time. This portal ends in a 'speaking ring' in Roland's world. During this crossing over, Susannah has sex with an incubus, distracting it while Eddie continues to carve the key which will allow Jake safe passage to Mid-World. Once the group is reunited, Jake's and Roland's mental anguish ends. Roland has now completed the task of bringing companions into his world.

Following the path of the Beam again, the ka-tet befriends an unusually intelligent billy-bumbler (which looks like a combination of badger, raccoon and dog with parrot-like speaking ability, long neck, curly tail, retractable claws and a high degree of animal intelligence) whom Jake names Oy, who joins them on their quest.

In River Crossing, a small, almost deserted town, Roland is given a silver cross and a courtly tribute by the town's last, ancient citizens.

The ka-tet continues on the Path of the Beam to the city of Lud. Before arriving there, the ka-tet hear the drum beat from the song "Velcro Fly" by ZZ Top playing from the city, although Eddie at first cannot remember where he has heard the rhythm before. Later the drums are revealed as the "god-drums" to which the inhabitants of Lud constantly fight. The ancient, once high-tech city has been ravaged by centuries of war, with the residents being divided into two factions: the "Pubes" and the "Grays". One of the surviving Gray fighters, Gasher, kidnaps Jake by taking advantage of the near-accident the team faced while crossing a decaying bridge (which looks like the George Washington Bridge of NYC). Roland and Oy must then track them through a man-made labyrinth in the city and into the sewers in order to rescue the boy from Gasher and his leader, the Tick-Tock Man. Jake manages to shoot the Tick-Tock Man, leaving him for dead. The ka-tet is reunited at the Cradle of Lud, a train station which houses a monorail that they use to escape Lud before its destruction brought about by the monorail's AI known as Blaine the Mono. The "Ageless Stranger" (an enemy whom the Man in Black warned Roland that he must slay) arrives to recruit the badly-injured Tick-Tock Man as his servant.

Centuries of system degradation have caused Blaine to go insane. Once the travelers are aboard, it announces its intention to derail itself with them aboard unless they can defeat it in a riddle contest. Blaine and Roland's ka-tet speed through the Waste Lands, a radioactive land of mutated animals and ancient ruins created by something that is claimed to have been far worse than a nuclear war, on the way to Topeka, the end of the line.

Twelve Guardians, which guard the Twelve Portals, are explained. Each Guardian matches up with a Guardian at the Portal on the other end of the Beam, and at the point where all the Beams meet is the Dark Tower. The Guardians are revealed in several scenes: the first is revealed when Roland is explaining to Eddie and Susannah Dean what Shardik was and his understanding of the Beams; another is revealed when Eddie and Susannah approach the Cradle of Lud; and the last, Bird and Hare, are revealed in the poem Roland and his lover, Susan Delgado, recite to each other occasionally: "Bird and Bear and Hare and Fish..." The only pairs identified are by Susannah and Eddie while at the Cradle of Lud.

Shardik was created by North Central Positronics Ltd., which may be connected to the mysterious Sombra Corporation.

The pairings as mentioned in the book are:

• Bear - Turtle
• Horse - Dog
• Fish - Rat
• Elephant - Wolf
• Lion - Eagle
• Bat - Hare
