climate change
Time to reread John Barnes' Mother of Storms.
What some of Amazon's guest reviewers say is true--it takes a while to get going, and there are a lot of characters. But neither of those are bad things, and I've thought about the book frequently since the tsunami. Considering that I must have read it at least five or six years ago--and I read a lot--it obviously works well enough as a story and a lesson that I've retained it this long.
