What I've read this year.
This one concerns the conflicts between a colony of humans on the moons of Jupiter and Uranus and the inner human worlds of Earth and Mars. A small black hole has wandered near the solar system and both sides want to control it for the unlimited energy it can provide. A pretty good read.
As near as I can tell, the excellent cover illustration has nothing to do with anything that happens in the book.
post about this book last week.
