The main issue with the sixth book in Stephen King’s The Dark Tower series titled The Song of Susannah is it is merely a bridge book between book five and the final one. It does not resolve the cliffhanger left at the end of The Wolves of the Calla but merely extends it into the final book, The Dark Tower.

Changing the Dark Tower Pt. III: Wolves of the Calla
Finally through the boring fire that is book three of The Dark Tower by Stephen King we leave Wizard and Glass behind to return to the main story of the series with the Wolves of the Calla and The Song of Susannah. Though not the best in the series the Wolves of the Calla is definitely the best of the later books in the series while The Song of Susannah leaves you wondering whether it is wholly necessary or wishing there was more.
