I just finished reading “Redshirts” by John Scalzi.
Redshirts is, of course, a term used by Star Trek fans, because in the original series, anyone, unknown, not in the main cast, in an episode was likely to die horribly or in a meaningless way.
Scalzi makes a nice satire over Redshirts who realize that this is a problem, and decide to do something about it.
A fun and enjoyable read, I will rate it 8/10.
