Jim, I'm so glad to see you mention Freedom. I'm reading it now, also, but you sound like you're farther along than I am. I've just finished the "autobiography" and am now into the following section with Richard and Patty at the vacation house. I really liked the first section, the happy Berland family, etc. etc. But then came the autobiography, and I assume Patty is the "autobiographer." And you're right, it is depressing, and the main character is a total mess.
I had it from the library, then bought it for my Kindle because it was really big and hard to read in bed and I had a couple holds coming from the library. Am reading other stuff now too, so it appears I'll get my Freedom in small doses. I'm not a nut case about finishing except for books I've bought at the publisher list price.
Patty is not like anyone I know. She is uniquely a mess.
