[Q]: It started with a great plot...until he actually wrote it. It was overwritten (it takes pages before something happens) and the protagonists were hard to like. Boring, sappy novel written as if he trying to imitate Victorian prose. There are a couple twists, but the main characters are such morons, it underscores the little action that does happen.
[A]: Negative


[Q]: The MP3 files downloadable from this site are not for Parsifal but Verdi's Traviata. Amazon needs to fix this urgently.
[A]:
Negative
