Has anyone read this book?

The author has created a very believable universe connected by wormholes. There doesn't even seem to be any causality violation, as predicted by other SF authors. Since the author has portrayed lightspeed delay as merely a superficial optical effect, what really matters in the Commonwealth Saga are the geometric positions of distant objects, not the apparent positions.

Relativity predicts that travelling FTL by spacecraft is not possible. But if we want to, say, travel to Mars, we still have to acknowledge that Mars travels in an elliptical path around the Sun at a regular rate. The apparent position of the planet, that is the image of the planet that we see through telescopes, is dependent on the lightspeed delay, and therefore on our distance from the planet. The further away we are, the further the image will appear behind its actual geometric position. As we approach, the image will catch up to the geometric position. So the apparent position of the planet does not follow the path predicted by orbital mechanics. It is the geometric position that does. And the light we use to "see" the planet is superficial.

So there must be something to this. If only we could connect two points in space. Or create a new spatial path that is shorter than the naturally-occurring one. Hyperspace. I guess I'm re-inventing classic SF concepts here.

Opinions?
