As for me:
Gregory Maguire: Admittedly he won me over with Wicked. The story, setting, and, oh God, the characters were all brilliant. Then I read Mirror Mirror and my adoration was sealed. I think what I love most about that one is his poetic use of language. The book reads like a giant prose poem. He writes the way I wish I could.
Ian McEwan: I thought my first taste was with Atonement, which I adore, but in fact I have since learned that Ian McEwan is the mind behind the script of The Good Son, of which I am also fond. I've since read a collection of his short stories and the disturbing book Enduring Love. He's a talented writer, of that there is no doubt. However, I think what appeals to me most about his work is the inherent cruelty, in particular toward his characters. I love how twisted he is, certainly earning the nickname "Ian Macabre."
Anne Tyler: My mother introduced me to Anne Tyler when I was young, knowing my love of strong characters. And that is precisely where her strength lies- in creating very real, very likable characters. The plots within her books are often simple, driven by the force of well-fleshed characters. My only complaint about her books is that, particularly in her early work, the endings often come across as being forcefully happy. I don't know if that was her doing or her editor's, but it is less a problem in her more recent books. If I had to pick a single book of her's to recommend it would probably be Dinner at the Homesick Restaurant. Try reading that and not loving Ezra. Just try.
