A really delightful and fast paced space-adventure-romance story. A friend described it as urban fantasy set in space, and that is spot on. You definitely see the sorts of tropes and story beats and fast paced writing style that you would in urban fantasy, except that it has been all been transposed into a sci-fi setting. And I don't know, maybe I should be jaded and literary and hard-sciency and look down my nose at that? But I really can't, I thought it worked wonderfully. There were developments that would been boring and cliched in a urban-fantasy novel, but that were great the first time you see them re-skinned, as it were, for this new setting.
Ok, enough about tropes, let me try to review the story directly. It's like Firefly! Except the story is told from the point of view of an awesome female version of Jayne, and the fist fights all take place in power armor/mechs, and there are interesting alien races and telekinetics and secret crew member histories, and oh no! Jayne has fallen in love! :) I'd like to single out the fight scenes for particular praise. Maybe it's just because I was raised on a diet of mech-warrior novels, but I thought that the author did a really good job with the power armor. Nothing is easier than writing a boring fight scene (I'm looking at you, Nexus), and I think the author largely avoids that, at least partly in thanks to the protagonist's Jayne-like love for her weapon systems.
Anyway, this book was about the same length as Scaramouche, but at least subjectively it took me about 1/10th the time to read. I'm definitely looking forward to the sequels. I wouldn't want all my sci-fi novels to be like this, but four or so like this would be great.
