I didn't expect much from this book--I was just browsing Kindle Unlimited for something to read--but this series turns out to be about the best thing I ever found there.
There are *countless* military sci-fi stories, and that's what I thought this was when I started--another knockoff of Hammer's Slammers, or Honor Harrington, or something. But no, there are actually no pitched battles in this book. None with guns and missiles, anyway. That's what made it more interesting, 'cause I'm kinda tired of the shoot-em-up stories.
The book (and the series, at least as far as I've read) is mostly about the command decisions of a fascinating character in a world that's more interesting than I expected. He has to fight through PR disasters, drug lords, pirates, stupid vacationers--you name it. It's told basically from the viewpoint of a complete novice to space travel, somebody who doesn't even know port from starboard.
This book (and the other books in the series) are pretty long, and I wouldn't call them "gripping". There is very little harrowing action. But there are plenty of interesting sidelights and tidbits about the universe that I found stimulating, and the characters themselves are very likable, the sort of people you'd like to have as friends.
