Middlesex and The Virgin Suicides, was coming out with a new book. In my review of Middlesex, I described it as "one of the most satisfying reading experiences of 2009 for me so far."
In contrast, The Marriage Plot was SO disappointing. It might even rank up there as one of the worst books I've read in 2011. The characters were annoying and I didn't like any of them. The plot was also pretty predictable and plodded along at a dreadfully slow pace. There was a lot of wordiness in the book as well, so I found myself skimming long paragraphs.
Middlesex is by far, the best book by Eugenides, so read that one, and please skip this one.
