I feel like what is happened, is that Liza and Feinstein have talked, he has written down many of the stories she's told, and asked her questions about her life. Then the third author is coming to compile, and string everything along, and tada! We have a memoir! I feel like it will be like Chita's. Nothing we haven't heard before, or talking bad about anyone. A fun read for her fans, which will be worth the $40/$50 cover price.
Can we survive with 3 icons (Barbra, Cher, and Liza) all having books come out in 3 years? Time will tell. I think Barbra is the reason we are getting the other 2 books.
