Query: An Appaling Book

This book is the worst I have ever seen for learning to paint in watercolors! The author and painter is ignorant and unskilled in the extreme. Most of her "paintings" are painful to even look at. Thank goodness I only checked this book out of the local library. Anyone genuinely interested in the beauty of watercolor is advised to stay as far as possible from this awful, awful book.
