Plot summary
Roland and Jake manage to make their way out of the desert, into lusher territory. They come across a Speaking Ring. At night, Jake is drawn to the ring by the Oracle contained within, but Roland saves the boy before the Oracle can drain him to death via sexual intercourse.

Roland restrains Jake at their campsite and gives him the jawbone taken from the skeleton in the way station, as a means of warding off the Oracle's influence. He then goes down to the Speaking Ring, taking mescaline to fortify himself. When he reaches the ring, he has a powerful psychosexual exchange with the Oracle, who tells him of Eddie Dean and Susannah Dean.

The next day they leave the campsite and eventually come to a mountain. The man in black is there, and taunts Roland, telling him they will speak on the other side. Roland asks Jake to make his choice as to whether he wishes to leave the gunslinger or accompany him, and Jake agrees to come with him, knowing that Roland plans to sacrifice him in order to reach the man in black.
