Roland's ka-tet remains intact, though scattered over wheres and whens. Susannah-Mia has been carried from the Dixie Pig (in the summer of 1999) to a birthing room (really a chamber of horrors) in Thunderclap's Fedic Station; Jake and Father Callahan, with Oy between them, have entered the restaurant on Lex and 61st with weapons drawn, little knowing how numerous and noxious are their foes. Roland and Eddie are with John Cullum in Maine, in 1977, looking for the site on Turtleback Lane where "walk-ins" have been often seen. They want desperately to get back to the others, to Susannah especially, and yet they have come to realize that the world they need to escape is the only one that matters.
Thus the audiobook opens, like a door to the uttermost reaches of Stephen King's imagination. You've come this far. Come a little farther. Come all the way. The sound you hear may be the slamming of the door behind you. Welcome to The Dark Tower.
