Wizard and Glass continues the story of Roland the Gunslinger and his ka-tet as they travel across Mid-World toward the Dark Tower. After their troubles with Blaine the monorail in the previous book, they are stranded in a version of Kansas where nearly everyone has perished from a plague (King fans will recognize this as the world of The Stand, and will recognize Randall Flagg when he arrives to give our brave wanderers a hard time). While the ka-tet walk across the barren landscape, trying to find their way back to the beam, Roland tells them the story of his past--how he came to be a gunslinger, about the woman he loved, and most importantly, about when the world started "moving on."
This book is more of a classic fantasy story, and has more in common with George R.R. Martin than with Carrie. However, it is still full of King's lush descriptions and lively characters. I was somewhat disappointed to have to leave Eddie, Susannah, and Jake's part of the story, but at the same time it was fascinating to find out why Roland has become the way he has. And the group did leave the past for a time in order to meet with the Walking' Dude/Crimson King, which was pretty spooky.
Once again, I recommend this book to anyone has enjoyed the first three, but it's absolutely incapable of standing alone.
