Derek, meanwhile, lived like a brochure for male potential. He drove a brand-new BMW, a graduation gift from Richard. He announced at dinners that he was looking at programs in California and London as if education were an accessory one ordered in the right city. Richard beamed at him with the easy pride of a man investing in his own reflection. My mother joined in quickly, learning Derek’s preferences, admiring his ambition, calling him driven and charming and full of promise.

I transferred high schools in the middle of junior year.

No one asks enough about that particular cruelty, I think. How hard it is to enter the last full year and a half of adolescence as a stranger carrying fresh grief and old anger in a school where friend groups have already formed and teachers already know who belongs to whom. I spent lunch periods in the library because it was easier to look studious than lonely. I learned how to move through hallways without expecting anyone to call my name.

At home, the Thorntons—because in that house I very quickly stopped thinking of them as my mother and stepfather in any emotionally coherent sense—performed family around me without ever really extending it to me.
