Diane Duane has been working with wizards, on and off, since 1983. Magic is a habit she just doesn't seem able to break: fifteen of her forty-five novels have magic in them, and all the rest feature science trying really hard to be mistaken for it.

Her interests, besides writing, include train travel, gardening, collecting restaurants, and staring at the night sky. Helping her do all these things (except the gardening) is her husband of twenty years, the screenwriter and novelist Peter Morwood.

Her favorite color is blue, her favorite food is a weird kind of Swiss scrambled-potato dish called maluns, she was born in a Year of the Dragon, and her sign is "Runway 24 Left, Hold For Clearance."

Her full biography is here, and her bibliography / filmography is here.
