A good book for people like me who haven't studied astronomy in a very long time and could use a refresher. Nice job covering some very common questions and misconceptions. And a fair amount of time debunking non-science of the Young Earth or aliens-among-us or astrology fans.
The only reason it took me so long to finish was Halloween Bingo interceded. I spent a month just getting other books out of the way to be ready for my bingo choices. Only to discover that the real horror is willful ignorance.
Fair warning, this is sixteen years old, so not exactly cutting edge. There are no gorgeous Hubble depictions of astonishing beauty. (I really like those kinds of books, too)
