Book V in the epic Dark Tower saga begins after escaping the alternate Topeka and the evil wizard Randall Flagg, Roland's ka-tet travel to the farming village of Calla Bryn Sturgis where they meet the townsfolk, as well as Father Callahan, who was originally introduced in 'Salem's Lot. He and the townsfolk request the ka-tet's assistance in battling against the Wolves of Thunderclap. Not only do Roland of Gilead and his ka-tet have to protect the Calla-folken from the Wolves, they must also protect a single red rose that grows in a vacant lot on Second Avenue and Forty-Sixth Street in mid-town Manhattan of 1977.
If it is destroyed, then the Tower (which is the rose in another form) will fall. In order to get back to New York to prevent this they must use the sinister Black Thirteen. And with Book V Wolves of The Calla, The Dark Tower is closer.
