As far as the audio book, this reader was not good. She tried to do a British accent and failed miserably. Just painfully bad.
As for the book itself, it started ok, then just got annoying. Obviously I know the book is about crazy rich people but it was really over the top annoying. After setting it aside for a while I went back and it got better. Also it took quite a while to remember the characters and figure out which ones were really main. By the end I liked it and will try reading the next in the series. I think it just took too long to establish that there was actually a plot. Once that got going it was fine.
