It might be Tangent by Gina Marie Wylie. Though it's been a long time since I read it
Description: Shanghaied across the time dimensions, middle school student Judy Bondi, her classmates and an extraordinary man deal with a history they never learned in school. Instead of reading history, they're making it! A fanfic set in H. Beam Piper's Lord Kalvan of Otherwhen universe.
