I'm enjoying this book. The pages on playing technique, fingering and scales are invaluable. The tunes are great, some of them new to me, but I would grade them a little more in order of difficulty as it will be a (long) while before I work on the upper register. It assumes the player can already read music well, which I can, but for basic tunes I have had to look at my childhood recorder playing books. Is there a "Tune a Day for Xaphoon"?
