Fun and not too demanding. Likable characters and a barrel full of witty repartee. Also a lot of fun references for a tv scifi geek. Not sure how I felt about the 3 codas that take up the last quarter of the book. In some ways they felt like filler with sole purpose of bumping this up to novel from novella. But they also had some interesting content. Overall I'd give this a resounding it was okay.
