Query: Wonderful for beginners!

I have always been interested in astronomy and just recently picked it up as a hobby. Terence Dickenson does a wonderful job conveying concepts to the average person. He has made it so easy to understand and so interesting it is difficult to put the book down. The pictures are perfect for those of us with little imagination. My ten year old is even reading it with me. Excellent!
