I decided to pick up on this series of books after only reading Boneshaker a few years ago, which itself was fun but sometimes felt a little clunky and sluggish. I wasn't expecting very much out of this one as the jacket premise didn't lend itself to improvement over Boneshaker. But I wanted something steampunky to kill a week or two of casual reading.
Pleasantly, it only took a day and a half because that jacket premise was deceptive and it really clipped along while expanding upon the world she started in Boneshaker, finally connecting in a really fun way that wasn't limiting.
It's possible to read these books without ever touching any of the others, yet if/when you get around to the rest she really rewards your interest. The bits that may have felt slow or clunky in one book pay off elsewhere and work to flesh out a very engrossing, detailed world.
It's a very underrated series, or anthology, and I can't wait to fill in a couple blanks and revisit this afterward.
