Revisiting Mid-world

I try to reread at least one or two of my favorite series each year. I know some people are forever going ahead, reading new books, but for me, there's a sort of wonderful joy in returning to these old series. So the first series revisit this year is the Dark Tower series by Stephen King. There will be spoilers. You have been warned.

I'm going slow, sprinkling these books in between book club selections and other reading. But I finished the first book, The Gunslinger, today (review at Goodreads) and had a few thoughts about Roland, Jake and the concept of Ka.
