Not much to say about this. It's your regular human race hero trip, which is suitable for Eric Flint who writes 'rah rah rah!' stories like they're candy. Yet where in his other series this annoyed me to the point of not wanting to read on, in this series it's not so bad (I suppose that's the influence of Wentworth).
Whereas I wasn't interested in continuing the 1632 series, this was entertaining enough to give the next book a try. If you like SF and light reading, you might want to give this a try.
