I think it won't get fixed for another day or two. The twelfth review is up on Goodreads and it's lovely - I hope Amazon does the right thing and puts them back - if I have to get involved be sure that I will.
"There’s something irresistible about reading other people’s letters and journals—it appeals to the voyeur in all of us. This is what Kimmel has tapped into in GEE, and it makes the book impossible to put down. It would've been too easy to do this as an epistolary work, and that would’ve created a distance for the reader. Instead, the third-person, spare prose simply mimics that of personal writing, which is much more effective as it allows the reader to go along for the emotional ride. GEE is not a novel one is likely to forget; it makes us think about life, the choices we make in it, who we are—and what we leave behind."
