Irina is the smartest girl in Gryffindor … and the most insufferable. Late-night
library excursions, rules bent, prefects antagonised. Tonight, Filch catches up
with her. She finds herself in a punishment room she’s never seen before, locked
into the stocks, completely alone with someone who has an unusual approach to
discipline.

Deeply satisfying for anyone who ever wanted to see the smug one finally squirm.
Irina learns that Hogwarts has rules. And some of them involve her bare feet.
