I had a hard time putting this one down, honestly. The storyline definitely unfolds more, and once you've started reading it unfolds rather quickly.
The ending was unsatisfactory, because of the cliffhanger-esque ending. Very much ready to read the 4th book.

The one thing that really keeps me from giving it 5 stars is that the setting keeps getting lost to me.

We're supposed to be 500 years in the future, but it really feels like it's set in the 1700-1800's. Yes, there are nods here and there to modern things and culture, but that gets lost in the "old world" piracy.

I love the story, though. That's what's kept me hooked in. :)
