Query: Rigorous... and Excellent!

This is an excellent "boot camp" for learning to read. It's rigorgous, but if you complete the exercises, you *will* learn to read. It's generally very easy to understand and is chock full of exercises. This isn't one of those "pay 20 bucks for a 40 page book that you'll be done with in a week." It's thorough and very economical. I've been consistantly working in this one for 3 months and it's greatly sharpened my skills. The only thing I think that could make it better would be an accompaniment CD. But this one gets 5 stars easily.If you want to learn to read, buy this book and be prepared to work.
