I thoroughly enjoyed this. John Scalzi takes the accepted knowledge about 'redshirts' and builds it into a funny and sometimes poignant look at the life of a redshirt from the inside, while still being a science fiction novel in its own right. The characters aren't all that deep for a good part of the novel, but there are good reasons for that. The story is engaging, and the humour, especially for those of us who remember the original Star Trek series, is spot on. Recommended to geeks everywhere, especially those who have fond memories of Star Trek, but are still able to acknowledge and appreciate its flaws!
