Who is Tanksy?

Fourteen-year-old Tanya Kofsky is invisible. She hates that no one listens to her, at home or at her new school. So as student elections get underway, Tanya starts secretly painting controversial images on the walls of the school. Soon everyone is talking about this amazing artist with a lot to say. The election results turn out to be a catalyst for more rebellion. And not just from students. Teachers, tired of the principal's authoritarian leadership, start promoting self-expression. Even the lunch ladies join in, ignoring the strictly controlled menu and serving more nutritious and culturally diverse fare. But can this revolution effect real change? Or will speaking up lead to complete disaster?
