I did. I liked it, and I plan on buying the book.
I wasn't surprised by the nasty quotes JK made. If anyone has read the Sarah Bradford biography on her, she was not only thin-skinned where critiques of herself were concerned, but throughout her entire life, she played "fake diplomacy" quite well (being nice to your face while making put-downs behind your back.)
I applaud Caroline for releasing it unedited though. (Which I think had more to do with the backlash for the previous "Jackie is so perfect in every way" books she's had a hand in, rather than because she actually wanted us to see JKO warts and all.) And for wanting to restore Jackie's place in the administration. I'm really happy with all the new Jackie books we've gotten this year.
