Is There Free Will in Heaven?

A new book just came out on hell. It's called something like sinners in the presence of a loving God. I think we will be free in heaven, although we will not be vulnerable to temptation because at this point in our history, we will have seen through the illusions of evil. But given the character they have formed, the only kind of choices they will be psychologically and emotionally capable of making will be good ones.
