I couldn’t breathe. The room spun. I didn’t read another word, not because I didn’t want to, but because I knew that if I did, I would shatter into a thousand pieces and never be able to put myself back together. I saw the scrawled margin notes, references to Room 214 and “Honors Advising,” and the name that made my blood run cold. Mr. Callahan. The man I had thanked at every parent-teacher conference for pushing my daughter to be the best she could be. The realization hit me with the force of a physical blow. I didn’t cry. I didn’t fall to the floor. I did what a mother does when the predator is in the fold. I grabbed my car keys, clutched that diary to my chest like a shield, and drove to the school.
