Loads of fun. It makes a perfect book for my "meta" shelf alongside Mogworld and Ready Player One. A group of people on an exploration starship begin to notice that their ship has an unusually high casualty rate among the "redshirts", and that casualties are directly tied to proximity to a few main officer characters. From there, it spins into a funny and intriguing look at the borderlines between entertainment and science fiction. Worth reading for any Trek fan, and especially for any Galaxy Quest fan.
