Ade loves living at the top of a tower block. From his window, he
feels like he can see the whole world stretching out beneath him.
His mum doesn’t really like looking outside – but it’s going
outside that she hates. She’s happier sleeping all day inside their
tower, where it’s safe. But one day, other tower blocks on the
estate start falling down around them and strange, menacing plants
begin to appear. Now their tower isn’t safe anymore. Ade and his
mum are trapped and there’s no way out . .
