This is the kind of novel you’ll think and talk about for a long time after you finish it. The plot is a bit hard to explain, because it involves six inter-related stories that take place centuries apart (including one I particularly loved about a young American doctor on a sailing ship in the South Pacific in the mid-1800s). But if you’re in the mood for a really compelling tale about the best and worst of humanity, I think you’ll find yourself as engrossed in it as I was.
