I just finished reading her first book. It is very interesting but she just talks about her life, where she lived, the trips she made, the people she met and a lot of weird experiences, but she never gets into much details. You're not gonna learn anything new except her story. The reason I bought the book is because I felt that she was telling the truth. And after reading it, I still think she does.
Steve_A, you say that she could be like one of the first hybrid prototype. It could very well be the case. Anyway, i'm gonna get into the second book pretty soon. In this one, she gets more into aliens, their technologies, langages etc... I'll tell you about it when I'm done.
