Earth
To be honest I wouldn't have finished this one if it wasn't a bookcrossingIE choice. I'm not sorry I read it but it was a bit too scientific for my real enjoyment and went down some avenues that I wouldn't have gone if I had a choice.
In a near future the earth is wracked with ecological damange and various land masses are under water causing mass emigration and more disaster. When some scientists find that there's a black hole eating the planet they're on a race for survival. Interesting but a bit too much science for my taste.
