See the world from another unique perspective in the thrilling new novel from the author of I Have No Secrets (a World Book Day title for 2018).

Nothing ever happens on Kasia's street. And Kasia would know, because her illness makes her spend days stuck at home, watching the world from her bedroom window. So when she sees what looks like a kidnapping, she's not sure whether she can believe her own eyes …

There was a girl in the window opposite – did she see something too? But when Kasia goes to find her she is told the most shocking thing of all.

There is no girl.

An eye-opening and compulsive page-turner for readers aged 12 and up.
