Found this in a charity shop today:
While I have all the previous Dark Tower books, I've actually only read up to IV (
Wizard and Glass), so I must start Vol V (
Wolves of the Calla) next.
I'm a bit out of touch though, as I read it a fair few years ago, and it took me so long to pick up the next in the series that I fell out habit and started reading other stuff instead. I think I've forgotten everything that's happened.
