Suddenly Lilli’s dad starts acting strange. He sleeps a lot, gets angry quickly, or speeds away on his motorcycle. Lilli misses the evenings when they gazed at stars together, having her dad all to herself, and ponders with Mo the cat whether dad is mad about something. But even her attempts to cheer him up don’t dispel the dark thunder clouds, and Lilli’s stomach starts to grumble and hurt. Then Papa tells Lilli about his black holes – and that he’s going to get help.
The book portrays the children’s feelings and worries and softens their fall. It shows how a parent’s depressive illness can affect a child and how important it is to talk openly about it with children.
