Wizard and Glass picks up where The Waste Lands leaves you hanging - in the clutches of Blaine the Mono. The action of the speeding train soon turns to a love story as we flashback to Roland's first love. I didn't realize what was missing from the first three books until I found it in the fourth - Stephen King makes me squirm. Rhea the witch makes me squirm.I'm happy to be reading this series. I feel pretty certain I won't recommend it to someone who wasn't already a Stephen King fan, but I do feel it is a must read for fans who haven't yet experienced the quest for The Dark Tower. I'm looking forward to continuing on with Wolves of the Calla.
