Donna Dewberry books

Hi guys, I've been thinking of getting some Donna Dewberry books.... does anybody have any or many of them? Are there specific ones you'd recommend? I've seen so many, but am a little confused as they all look like they may contain the same or at least very similar content.
Any tips or reviews are greatly appreciated

I have two of her books, that I bought about two years ago, shortly after I started painting, to learn her technique. One is called Donna Dewberry's Essential One-Stroke Painting Reference and the other is Donna Dewberry's Complete Book of One-Stroke Painting.
What are you looking to get out of the books?

Thanks for the reply I am not artistic at all really, so I'm wanting to learn how to paint flowers for one thing... and basically learn the strokes required to accomplish something anywhere near decent-looking

I'm only looking to further my facepainting skills for that matter, am not really interested in painting on any other types of surfaces.

I have the Essential One-Stroke and All New book of One-stroke Painting. I love books. Both are good but I have to say that I like the second one a bit better. All her books are nicely illustrated and explained. They are primarily craft books though and so the medium is different.
