A girl called Hana has a new step-brother. Her mum married his dad, and now he lives in their house half the week. He's quiet, polite, and clearly uncomfortable. He doesn't know where the cups are. He waits to be told where to sit. He calls Hana's mum by her first name, carefully. Hana didn't ask for any of this. Part of her wants to be welcoming. Part of her resents the stranger in her home, sitting in what used to be just her family. He hasn't done anything wrong. But every time he's there, the house feels less like hers, and she doesn't know what she's supposed to feel.
