I got a free copy to review. I liked it (as far as those types of books go). It is very popularized and includes info on the history of comets, the "guts" of comets, and tthe discovery and hoped visiblity of Hale Bopp. Would this book ever be written without the hullabaloo over Hale Bopp? Probably not. But if you take it for what it is (a layperson's guide assuming nothing), it's a nice little book.
