This review is based on an ARC received from the author.
This was a page-turner for me, a tasty bit of alternate history fiction with an unusual setting. The main character is from a seagoing family, and so much of the novel had to do with trade and sailing. Callista is a very enjoyable character, as were the others.
For me, the book had two weaknesses.
First, the chapter-heading artwork was inconsistent in quality. For instance, the illustrations at the beginning of chapters 8 and 18 were extremely good, but the quality dropped way off whenever people were the central focus of the illustration. That's a production issue, though, not a literary one.
Second, the alternate history was intriguing, but frustrating. Usually, the author of an alternate history provides more clues about the world. In this one, the American Civil War doesn't seem to have occurred until the late 1880s, and dirigibles are very advanced. Somehow, it is still economically viable to have transatlantic trade via sailing ship, even though steamships are relatively common. I'd love to have learned more about how any of these things happened, much less three seemingly unrelated things in the same story world.
So, I kept reading because of the interesting adventure story and the characters, but I really wanted more out of the world-building.
