Ensign Andrew Dahl has just been posted to the Intrepid, the flagship of the Universal Union fleet. It's a prestigious post, but when Dahl arrives on board, he finds that life aboard the Intrepid is just a little... well, strange. To start off, it seems like the crew avoids their senior officers. Those that don't tend to get assigned to away teams, and those assigned to away teams... often end up dead. Then there's the Box, a device of unknown provenance that consistently offers solutions to insoluble problems just in the nick of time. Something isn't right on the Intrepid, and Dahl and his friends are going to get to the bottom of it - even if it means their world will never be the same.
Scalzi has written a fast-paced, entertaining narrative great for fans of Star Trek and similar sci-fi shows as well as people who enjoy a healthy dose of "meta" in their fiction.
