Song of Susannah (The Dark Tower, Book 6) Review

Yep, a review already. I tend to devour my Stephen King books when I'm able to devote some time to them and they don't gross me out so much that I can't eat my lunch. I picked this one up at the library last Wednesday and finished it last night.
There's not much to really review here. I'll probably save a more substantial review of the whole series for when I finish The Dark Tower 7. This book was mostly a bridge from the "Wolves of the Calla" ending to the final book in the series. Of interest though is the fact that King inserts himself as a character in the book! It's a bit contrived, but when you look at the "ad-card" (the list of books by the author) and see how many of his books are Dark Tower-related, you can see why he did it. It's consumed his literary life to the point that it was a theme in the majority of his books. He probably could have written the book without putting himself in it, but I'll reserve judgment until I've finished the series.
Aside from that, it was a lot of typical King/Gunslinger stuff. The group of gunslingers gets split up (a device too commonly used, see the review of "Eye of The World"), and go on separate missions in their quest to save (?) the Dark Tower. It concludes with a fully expected cliffhanger, which is fortunately made easier by the fact that the final book was published only a few months after this one. Luckily for me, I should be able to go right into the library and get the final book and finish off the Dark Tower.
Next up, duh, The Dark Tower 7.
