Domestic Magic — Kristine Kathryn Rusch

At a high school for the magical, the most picked-on kid dreams about J. Rutherford Wisenhaur II killing people with a fire spell. She knows her nightmares portend the future, but her domestic magic lacks the power to do most difficult spells.

To make matters worse, no one will believe her. So, what's a young, nearly powerless witch to do?

“Rusch is a great storyteller.”
