#50 Zoe's Tale by John Scalzi

This books runs along the same time frame as The Last Colony. Everything is from Zoe's point of view instead of John and Jane. The plus is that you get a slightly different take on stuff if you have read it before and if you haven't read Last Colony this is also a good jumping in point. IT is also a good ya novel to recommend to friends without having to worry about something might offend in it.
