This is purely entertainment. Don't think too deeply or you'll be disappointed. I read it to keep my mind off a cold and it did that. The main character is a bit hard to accept as the intelligent woman she is supposed to be. She is guilty of being stupid if anything but again, this was fun and light and well-written. Oh, that we all could be wealthy and have wealthy friends and all end up happily ever after.
Read it for fun---not for depth and you'll be just fine.
