Written : 1996 - 1997

Synopsis :
Roland finds himself in a deserted town, or so he thinks at first. Finding a young dead boy, he sees a gold necklace, and takes it to look closer, but is savagely attacked by green mutants before he can look closely.
He is nursed back to health by the Little Sisters of Eluria, but all is not as it seems, as the sisters have strange powers, and a taste for blood!

The book and subsequent series was inspired by the poem Childe Roland to the Dark Tower Came by Robert Browning.

The Little Sisters of Eluria is a short novel of about 80 pages. It takes us back to a time when Roland was still on the trail of the Man in Black, long before we first meet him in The Gunslinger. As far as I know, Little Sisters will not be Part of Dark Tower V, and it's uncertain if it will ever make into any of the forthcoming novels.

Personally, I find this unlikely because I don't see how it could fit into the storyline, assuming we will be learning more about the future of Roland's quest (i.e. following the main plot) in the next installments, instead of further flashbacks to the past. Also, since King seems to be tying more and more of his works to the Dark Tower saga (at the latest, Little Sisters connects Desperation to Roland's World), it would seem quite reasonable to see more closely related stories like Little Sisters appear out of the line of the Dark Tower Books.
