All action stories need minor characters who are somewhat expendable. When bad things happen to them, it makes the danger feel more real and raises the stakes for the heroes. In science fiction the label redshirts has become shorthand for these doomed roles, and John Scalzi has imagined a world where they refuse to play along with the script. Redshirts: A Novel with Three Codas is both a hilarious adventure in space exploration and a playful tribute to the quirks of serial storytelling. Fans of the films Galaxy Quest and Stranger Than Fiction will find this an appealing mix of affectionate nitpicking and fun reinvention, especially as performed by veteran sci-fi actor and author Wil Wheaton.
