Scardown by Elizabeth Bear (Jenny Casey 2)

For being about the worlds first FTL ship its a lot about earth and staying in orbit.

More about the interesting alien tech is revealed in this novel. International tension rises as Canada and China race to be the first.

There are many aspects to this book, I like the ecological aspect and the aliens that comes to visit. I would hate to live in the world she paints, but it is very realistic.
