I read "Wool" the book several years ago and was very impressed that such an interesting book was self published.
It is interesting to watch as "Silo" because the sets and the actors bring the book to life for me. (Even so I had somehow thought of a narrow iron staircase rather than the wide stone? staircase in the series.
In a sense I wish I had waited several months before starting to watch. Souvj happens in the book, and only 5 episodes are listed.. surely there are more to come.
Well worth watching.
