Wolves of the Calla

Stephen King's best book to date, and I've read 'em all. Read this series if you're looking for a well crafted tale.

This is the best that King has to offer in his massive collection of writing. He continues to build the suspense with the 5th book in the Dark Tower (DT) series and, quite frankly, makes it the most important book of the seven, by having this book set the tone for the remaining books of the series.
