It starts, as most disasters do, with firewhisky and poor decisions. One Friday night in sixth year, the boys slip into the Room of Requirement with something to drink and nowhere to be. Somewhere between the second bottle and the third, the conversation turns honest. They start talking about the girls — what they don’t understand, what they wish they did. Mattheo Riddle says almost nothing. Except once, quietly, he says a name. The Room, which exists to give people exactly what they need, takes note. By morning, Beatrice Kelly wakes up in the wrong body, Pansy is wearing Theo Nott’s face and is furious about it, and Daphne Greengrass is touching her new stubble with the quiet devastation of someone whose entire world has shifted on its axis. Chaos, naturally, follows. In Someone Else’s Skin is a body-swap story about what happens when you get exactly what you wished for. It’s about seeing someone from the inside and not being able to unsee it. It’s about a boy who has spent a year hiding something behind charm and carelessness, and a girl who is far more than anyone — including him — ever looked closely enough to notice. Funny first. Always funny first. But underneath it, something real.
