If you like the idea of 50 shades, I have been recommended a book called Bared to You by Sylvia Day. It's similar in context, the writing is supposed to heaps better!
I didn't like the shopaholic one - I only read one (the onewhen she has a baby) ... I liked her "undomesticated goddess" book, though. Very funny
But hey, with other Paullina Simons books, have you read "A Song In The Daylight"? I didn't like her "Road to Paradise" much, so haven't got around to ASITD, but now her new one is out, and I'm one behind ... Have you read it? What did you think?
