Mrs. Kerr

Mrs. Kerr was a perky blond woman who became the pre-algebra teacher at Yancy Academy. She replaced Mrs. Dodds after Mrs. Dodds, who turned out to be one of The Furies, was disintegrated by Percy in the museum their class went to as a form of a field tip in their Latin class, ran by Mr. Brunner ( a.k.a. Chiron). Through the interference of the Mist, the veil that shuns away all the magical things happening the world, the mortal students believed that Mrs. Kerr has been with them since the first day of the school year, and perhaps Mrs. Kerr herself thought so too (as the Mist can create memories).
