I absolutely adore Gregory Maguire. He's best known for his Wicked series--which is Fantastic, if you haven't read them, get to a bookstore now! I also have to give a shout out to one of his (slightly) more realistic books, The Next Queen of Heaven. It's a funny and beautifully written tale of kindness and self-discovery.
Since Mr. Maguire is also an adoptive parent, I love him all the more. Below is a recent interview he gave. His remarks about his kids keeping him grounded really made me laugh!
