I got about 3/4 through the book before I gave up. The thing that made me give up was how much I was just not enjoying the book and the characters. It even seemed that the author didn't like his characters and held them in contempt. It was this more than anything else that made me realise I couldn't care less what happened in the book. The author certainly didn't seem to.
I am a big fan of Franzen. I agree with an earlier reviewer that the narration of Freedom is a spoiler. I was happy to quick-march though the book in its audible version and went on to buy a hard copy and read it again. Not only does the narrator characterize Lolitha with a bad approximation of her accent, it is difficult to sympathize with the wife because of the narrator's vocal characterisation. I got a completely different impression reading it.
I have found this true for several audible books and would greatly value recommendations from other audible "readers" of books which are delightfully interpreted. Jeremy Northam reads George Orwell's "Down and Out in Paris and London" deliciously. Mary Gordon's latest book "The Love of My Youth" was also badly narrated. I found "The Maids" well read.
