My Name Is Leon by Waal Kit de

A brother chosen. A brother left behind. And a family where you’d least expect to find one. 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, since Jake is white and Leon is not.
