The Witch of Agnesi: Book One in the Bonnie Pinkwater Series

Bonnie Pinkwater is a teacher, a good one. She cares about her students. So when Peyton Newlin, a thirteen-year-old math genius, disappears, Bonnie starts nosing around. One by one, students who were competing with the young genius start turning up dead and Bonnie suspects Peyton may be narrowing the field. Then Peyton himself turns up murdered. Bonnie's investigation ratchets up.What she discovers is a coven of witches, a teenage comic book magnate, a skinhead Neanderthal with violent propensities, an abusive father, an amorous science teacher, and a mistranslated medieval mathematics manuscript. Somehow, all the pieces have intersected at the tragically brief life of her math protégé. As the body count mounts, Bonnie realizes she may have bitten off more than she can chew. Because whoever is eliminating her beloved students, has now decided East Plains, Colorado would be better off without one aging math teacher.
