The Book of Stones is an excellant well, rounded look at crystals.  It covers the scientific aspects and metaphysical aspects of crystals, along with beautiful photographs.

Love Is In The Earth is really a two volume set, with the second volume being a pictorial.  Lot's of interesting methods of using crystals more than one option  for performing the same task in many cases.

Abraham's newest book, The Vortex, Where Law of Attraction Assembles All Cooperative Relationships,  will help you understand every relationship you are currently involved in as well as every relationship you have ever experienced.

       This book uncovers a myriad of false premises that are at the heart of every uncomfortable relationship issue, and guides you to a clear understanding of the powerful creative Vortex that has already assembled the relationships that you have desired. Abraham will show you how to enter that Vortex, where you will rendezvous with everything and everyone you have been looking for.

I found this book made the concepts of manisfestation and understanding the opportunity in relationships easy.
