I wrote "The School up the Hill" for SWORD OF ICE, the first of Mercedes Lackey's Valdemar anthologies. She's still doing the anthologies; I just sold "A Leash of Greyhounds" to UNDER THE VALE, which will be published this December. As frequently happens to me, the idea came from a casual reference in one of her books about the teachers from the White Winds mage school coming down to the village to fix any damage done by the students. One of my favorite things about writing is that I can ask the question "what if...?" and then go off at a tangent.
"The School up the Hill" is available for Kindle and Nook.
