Jesika is four and a half. She lives in a flat with her mother and baby brother and she knows a lot. She knows their flat is high up and the stairs are smelly. She knows she shouldn’t draw on the peeling wallpaper or touch the broken window. And she knows she loves her mummy and baby brother Toby. She does not know that their landlord is threatening to evict them and that Toby’s cough is going to get much worse. Or that Paige, her new best friend, has a secret that will explode their world.
