I grew attached to some of the characters in this novel and I'm so upset that Overdrive doesn't have the next book in the series. The Dark Unwinding definitely ends with a cliffhanger and I cannot wait to read [b:A Spark Unseen|17320980|A Spark Unseen (The Dark Unwinding, #2)|Sharon Cameron|https://d202m5krfqbpi5.cloudfront.net/books/1361342958s/17320980.jpg|24017642].
I agree with some other reviewers that it's not very steampunk-ish. There are clockwork toys involved, but that's not the main focus of the story at all. This is more of a creepy Victorian mystery novel.
