Author

T. Kingfisher is the vaguely absurd pen-name of Ursula Vernon. In another life, she writes children's books and weird comics, and has won the Hugo, Sequoyah, and Ursa Major awards, as well as a half-dozen Junior Library Guild selections. This is the name she uses when writing things for grown-ups. When she is not writing, she is probably out in the garden, trying to make eye contact with butterflies.
