Just finished the first book of Wool. The Wool series, which has already become a classic of modern SF, began life as a short story in 2011, and which now includes seven books (with volume 8 and 9 in the works). Plus Ridley Scott has assumed the film rights. A terrific read, and I think it will appeal even to the non SF crowd. Thankfully, I have bought the omnibus edition with volumes 1 to 5, so there remains a good deal more to read. The book was originally self published through Kindle direct, so it is only appropriate that I read it through Kindle as well (though I did it mostly through the cloud reader+android app).
