I got a gift card for Amazon for Christmas, and I really want to order some good and helpful books. What have you read that's been helpful? I purchased and read one ("The Goat Handbook" a Barron's book), but it was written at an elementry school reading level...I don't think the information was bad, just the writing was pretty elementry. I love to read - and want to learn more...but don't want to keep buying books that aren't helpful. Thanks, guys!!
