Detective Inspector Mina Wentworth is called to investigate a frozen body that has appeared on the Iron Duke's estate. The Duke is the alpha-est male around and, as this is a romance, he falls in lust-at-first-sight; as this is a romance, she is filled with doubt, fear and distaste, and rebuffs him. Circumstances force them together and she gradually, but inevitably, falls in love, or at least bed, with him.
The circumstances are the interesting part, and they include: a pirated naval airship, the capture of Mina's brother, the invasion of the fortress of a mad inventor, a run through a zombie-occupied forest, a trip on a mercenary corsair airship, and the fears that the Eastern Horde has a mind control device and renegade English Black Guard are almost ready to use a weapon of mass destruction.
It's not one of those books where you stay up till 3am while saying "just one more chapter", but the setting is interesting. The characters look like they have the potential to be interesting, but don't quite manage it, leaving unanswered questions like "why is Archimedes Fox exploring zombie-infested Venice?" and "Why is Yasmeen a corsair?" and particularly "why is the Iron Duke so hot for this policewoman?" The sex scenes are both explicit and boring. We found out who dropped the frozen body, but if we ever found out why they did it, I didn't notice it. And there was no overall antagonist; for a couple of chapters the heroes were chasing one person, then they went off another another, then a third, then a fourth, and there was no sense of "there's a mastermind behind it all", just a jumble of "who has the McGuffin at the moment?"
I finished it, but I don't feel any desire to read the next one.
