If the title didn’t tip you off, Redshirts is Scalzi’s loving parody of Star Trek. All the familiar characters and tropes are there, even if the names have been changed to protect the (not so) innocent. I found it to be a fast and hilarious read – if anything I kept having to stop to read portions to my longsuffering wife. The 3 codas add a nice balance to the book with their poignancy. Highly recommended.
