Hello Kelly; I would to go on the record as saying that I haven't heard of either of these books and having 2 teenage girls (19 and 12( I found myself overwhelmed with explaining the concept of what was going on with my 12-year old when she started to evolve. I didn't have the same difficulty with my 19 year old daughter as I was able to draw diagrams and draw upon my sight to help with explanations. so, I will be downloading the books that you speak of to read for myself as well as purchase the same copies in text format for her.
