While this definitely wasn't a perfect book for me, I still highly enjoyed it. It's fast-paced, and full of plot and characters. I love a book that just never stops, and this was IT. I was a bit disappointed in some aspects; often i found that there wasn't enough political background explained (and I hope the finished copy comes with a map!), and I found at times the characters weren't doing what they should've based on their development so far in the story.
I'm not sure that I'd call it steampunk, because we don't see enough technology for that, and there's no magic system to really call it an epic fantasy, but it's like a Ace of Shades meets Six of Crows type of book, and apparently it's a retelling of The Count of Monte Cristo, but I've never read that so I couldn't tell you how close it comes.
But other than that, there's sailing (yes!), dark casino dealings (heck yes!), and some steampunk-ish, fantasy-ish fun (triple yes!).
We'll see when the sequel comes out (likely is 2021?) if I remember this one enough to read the sequel, the ending definitely warrants a sequel to wrap up basically anything, as we're left with very few answers, but only time will tell how memorable this is for me.

Thanks to Edelweiss and Disney Hyperion for an e-arc in exchange for honest review!
