Ah, redshirts. It seems to be a sign of a true SF geek to immediately get the reference, vs those would stare at you blankly if you referenced it. But what if you suddenly realized that you weren't the main character in the reality that you inhabit. Worse, you come to the suspicion that your part in the show may be to become just interesting enough to make the audiences feel some emotional loss when you died. And everyone around you is dying at a rate unheard of for any other ship in the fleet.
Well, this is what happened to the main characters of this story. And after living through a dreaded away mission (except for their dramatically lost friend ironically) they finally figure out what is going on and even when their show is being written (though of course via divergent universes there is no reference to their show). After kidnapping a main character (one of the best ways to ensure that they don't die off-screen) they are off to the past to try and stop the writers from killing them and their compatriots.
Overall a fun book, with entertaining characters and a sly wink to a bunch of in-jokes. It may not be a book I ever go back to re-read but it was an interesting story.
