Agree. I have read it 3 times. I was really into to the Dark Tower but the long time between 3 and 4 lost me.
The lag between 3 and 4 was long. Then I got volume 4, picked it up, put it down, and then picked it up later an couldn’t put it down again. Out of all 7 of the books, Wizard and Glass and Wolves of the Calla are my favorite, and my favorite plot scene is the ultimate drawing of Jake through the mud door in The Wastelands.
