Book Club discussion

So the Dark Tower train continues. I guess the plan is to run through this whole series because I'm in too deep now. Also is pretty good airplane reading and should work well on the beach as well.

This book started off by addressing the whole time travel question I was asking at the end of the last book. So, that's a thing. And a lot of stuff is happening.

Otherwise I'm not even sure what to say about the book.

Roland - The gunslinger and grizzled veteran who brings the team together
Eddie - The jokester who will need to face his inner demons and make some serious choices
Suzana - Has already overcome personal demons, but has physical limitations... So probably represent the moral center of the group. Also Eddie will need her to overcome his thing.
Jake - The youth of the group. Represents the future and the world moving on and away from Roland maybe? Also some sort of angle with "will Roland kill him?" Ultimately will be the barometer of Rolands personal struggles.
Oy - The lovable rapscallion. Probably disposable for some sort of growing moment for Jake. Or won't because he's part of the ka-tet?
