Nice progression from The Iron Duke but I prefer it, both characters and plot. I did enjoy Heart of Steel, though it didn't feel as tight as The Iron Duke.

I enjoy the Steampunk setting being a fan of the genre, but I felt the character could have used a bit more development in order for me to feel as engaged as I did with The Iron Duke.

Good second novel in the series and will look out the the novella's, short stories and third book.
