Most complete and thorough book ever written on the subject.
As a professional numerologist, I have a whole book shelf full of numerology books. But none of them are written as concisely or contain the depth and detail as "Numerology: The Complete Guide," by Matthew Goodwin. Of all the numerology books I own, this is the one I consider my bible--that I refer to all the time. It is the only book out today that actually shows you how to do an integrated reading. All other books I have ever seen leave it to your intuition and experience to figure out how to do a professional reading. And the well written and organized tables at the back of the book make the information easily accessible. Though this might not be the best book for a beginner, it certainly is the best book ever written on the subject and is well suited for the intermediate and advanced students of numerology. Another benefit of this book is that if you own one of the several numerology software programs written by Matthew Goodwin (available from Widening Horizons), then you'll find this book of great value in better understanding how the detailed and in-depth reports are constructed.
