Just finished reading (yes, already) The Soprano Sorceress, which I got for Christmas (thanks d0om!). Not a bad book, all in all - but the one thing that made me want to throw the book out of the window was a very badly botched opera aria quote. Either the author didn't do his research, or his editor wasn't worth anything. Sigh. It's not that difficult to check for proper spelling and wording...
[EDIT] I was googling for the book title, to see what other people thought of the book... and look what I found. Freaky.
