Query: Great and Helpful Book!

This one of the only yeast-free recipe books out there, and it is a must have for those that are doing the yeast free diet, or are living yeast free! Jane Remington's recipes are simple to make, and complex in taste. My family loves the recipes I have made so far, and more than anything, I am grateful to have an easy-to-use guide. I highly recommend this book, even if you are not doing yeast-free living!
