Knowing that this was originally published (and is still available as) five novellas/short stories, I'm having a difficult time rating it as a whole.

Wool -- 5 stars. A GREAT story. I can understand why fans wanted more.

Wool 2: Proper Gauge -- 4 stars. It took me a little longer to get into this one, but (again) the ending grabs you and you MUST keep reading.

Wool 3: Casting Off -- 5 stars. Possibly my favorite. Juliette is such an awesome character.

Wool 4: The Unraveling -- 4 stars -- We start getting real answers, but it lost the urgency I felt with the first three stories, but I never once thought I would put the book aside. There's TOO much I need to know!

Wool 5: The Stranded -- 4 stars -- We've got answers, we've got heroism, we've got bravery, we've got truth. It's awesome and (I feel) complete. I wouldn't mind more stories from the Silo, but I think the author did a great job of telling this story completely.

I read a couple of reviews that mentioned the title...and I think it makes sense. Part of why I wanted to read this is because the title was so random. Points to the author for grabbing my attention!
