I checked this book out at my library.
However, a nit-pick, if you'll allow it. I couldn't help noticing that the timestamp on the chapter headings reset to zero at some point and was zeroed out for each chapter thereafter. I don't think that was deliberate. I suppose I only noticed because I like to read that stuff, and to have a sense of the story's timeline as it moves forward.
Concerning Character: Durango is a fun character to follow, as we gradually discover his unusual backstory and the various skeletons in his closet. The author does a nice job of developing the character of the protagonist and revealing more and more about him without skimping on action and forward movement. The side characters are mostly foils for Durango, providing a few obstacles and a liberal dose of humor and comic relief—except for his second-in-command, the dangerously hot Vienne, and his AI implant Mimi, who has a whole backstory of her own.
Recommended for Fans Of...: If you liked the TV series Firefly, you might like the feel of this one—like that show, this book provides a backdrop where anything and everything crazy might happen, out at the frontiers of human space settlement. It may also appeal to fans of other space sci-fi with YA appeal, like John Scalzi's Old Man's War books and Across the Universe by Beth Revis (reviewed here), and fans of humor-infused Mars sci-fi series The Company by Kage Baker.
Themes & Things: Durango's struggle against the pressures of family loyalty versus the need to do what's right and follow the Regulator principles he believes in makes him a layered character, and his internal conflict informs the story throughout. The book also poses the question, are all bets really off, even when you live in a wild and out-of-control society? What about your innermost ethics? We find out what Durango's made of when his limits are tested in a variety of ways, on a foolhardy mission that seems doomed to fail.

And, hey, one more thing—it sounds suspiciously like his next book, Invisible Sun, might be a sequel (and it echoes ANOTHER great song in its title, thus guaranteeing that I will need to read it).
You can find Black Hole Sun at an independent bookstore near you!
