Query: Good introduction to acrylics

For someone just starting acrylic painting, I thought this was a good introductory book. It describes acrylics, materials (such as brushes) and various techniques. I thought the sample projects were a little complicated for a beginner. The rest of the book seemed geared to someone just starting acrylics, but the projects seemed more advanced.
