Maybe a book about movies!
Or a book that may soon be a movie, like Inherent Vice, which is what I've got lined up after Tree of Smoke.
I just finished Tree of Smoke actually. I liked it, but I wasn't blown away by it. Part of it was the details, I've been to the the Philippines and Vietnam quite a bit and am very familiar with the cultures and it didn't feel authentic, even for the time being portrayed. Basically, I couldn't suspend my disbelief and become immersed in it. Also, the use of Vietnamese in the book was pretty bad, but whatever.
Certainly don't intend to judge a book without reading anything but the synopsis, but I really don't approve of airing other peoples' private business to make your book a bestseller (though of course she had enough of her own to talk about, I'm sure). Should I live my life assuming that everything I say or do might be written down by one of my friends later if they or I get famous? Maybe, but that's sort of constraining. That said, I'm sure it's a fascinating book and I'll download it if I get the chance.
