Ursula Vernon writes books for younger children, for the most part. I like them. (No cracks about second childhoods, please, I took care not to leave my first one.)
She was recently a Guest of Honor at Chessiecon 2015, sharing the limelight with Seanan Mcguire. Her middle-grade book, Castle Hangnail, has been optioned by Disney (but they option lots of stuff, so I'm not holding my breath waiting for a movie). She has a long series (just completed) for younger kids about Danny Dragonbreath. Her new series is about Hamster Princess. She also writes adult-level stories. Some of them are published under her pseudonym, T. Kingfisher.
