To start off with the good: the characterization seemed to be pretty good (with a few exceptions), but I think I got this impression mostly because the book borrows heavily from the text of Pride and Prejudice. It's a funny and easy read though.
Now on to the bad: The plot is totally implausible (although there is not even very much of a plot at all) and the ending is as stupid as it can be. The punctuation is bad and there's a lot of tell instead of show.
In the whole I'm glad I bought the book only used.
