Not the book for me and I'm not exactly sure who it is for. I was hoping for a book about astrobiology. I got that. But also got short introduction to just about everything in science, whether or not it was relevant to the topic, from dark matter to evolution to geology to the multiverse. As a result I didn't learn much.

That said, the book is comprehensive and the chapters on the solar system and the search for extra solar planets are reasonably interesting.
