I really liked the premise of this book. Jane is an eight-year-old child with an adult imaginary friend. He means everything to her because she is neglected by her mother. Michael is a "real" imaginary friend. It's his job and he has all the powers he needs associated with such a job, like being visible or invisible to whomever he chooses. This was a quick, easy, fun read. Predictable and fluffy could also describe it well, though. I enjoyed it as I read and had a hard time putting it down but when I was done, thought, there wasn't much substance to it. There is a sex scene that I skipped and a half dozen f-words to spoil it, too. Another thing that bothered me was the cover. I think it's a beautiful cover, but Jane is a blond and I had a hard time picturing her right because of the picture of this dark haired woman.
I've seen a few reviews for this one that were quite derogatory, calling it too predictable, dumb, etc. Others really liked it. I didn't think it was that bad and I did enjoy it while I read. So Sundays at Tiffany's will be classified as a "read at your own risk" book. I'd be interested to hear what you think if you've read it, or tell me if you think you might read it.
