Best Hoffman Book To Be Made Into A Movie

So far, there are film versions of three of Hoffman's books: Practical Magic, The River King and Aquamarine . Which Hoffman book do you think would make a good film?

Having read only 3 I would like Blue Diary, as that is the one I most enjoyed.

The only film version of her books that I have seen is the one made from Practical Magic and I enjoyed it; thought parts of it a little more than strange/bizarre but enjoyed it.
The book of hers I would most like to see made into a film is probably Property Of. I believe this was her first novel & is about street kids/gangs & is really different from most of the books she went on to write. I didn't know if I truly liked the book when I read it, but there was something absolutely fascinating about how she wrote the characters. But then I suppose with Hoffman, there always is.
