Hi butterfly, I believe in those books so much, that if I had the money I would buy a set of those books to everyone in the world!
If you do not have the money now, you can try going to your library and if they do not have them, asking them to order them to you from another library, they have done that many times before in many places in the United tates.
I mean like the smaller libraries do not have them, so they have them send from another library in another county. You can try that and see, that way you can save the money and buy them later. Good luck! Lots of love, light and hugs.
