A startlingly original, stunningly-illustrated modern classic about learning to face your fears from the multi award-winning partnership of Nick Lake and Emily Gravett. Lily just wants things to go back to the way they were: before she got sick, before her parents decided to have another baby. So when she's sent away to stay with her grandmother while her mum has the baby, Lily is determined to go home.

But she doesn't expect to find people in her house - people who look like her parents, but definitely aren't ...

Together with some unlikely animal companions, Lily must face her fears and summon the courage to break into her own house, and defeat 'The Replacements' before the night is out. Nick Lake's atmospheric story of family and friendship is brought to spectacular life by Emily Gravett, twice winner of the Kate Greenaway Medal.
