In the way that Galaxy Quest is my favorite Star Trek movie, Redshirts is my favorite Star Trek novel. That is, they don’t technically take place in the Star Trek universe, but close enough. And they’re hilarious.
As one of the most popular franchises in movie and TV history, Star Trek is not lacking for extensive and thoughtful source material.
As of November 2019, approximately 850 novels, short story anthologies, novelizations, and omnibus editions have been published.
Star Trek books are often ignored (sometimes rightly so) by review sites like Kirkus Reviews and Publishers Weekly, so you’ll have to decide for yourself if a certain book sounds like your cup of Earl Grey tea (hot).
