Leon is nine, and has a perfect baby brother called Jake. They have gone to live with Maureen, who has fuzzy red hair like a halo, and a belly like Father Christmas. But the adults are speaking in low voices, and wearing Pretend faces. They are threatening to give Jake to strangers. As Leon struggles to cope with his anger, certain things can still make him smile - like chocolate bars, riding his bike fast downhill, burying his hands deep in the soil, hanging out with Tufty (who reminds him of his dad), and stealing enough coins so that one day he can rescue Jake and his mum.
