A kiss, a dare and a boat called Promise - Fiona Foden

A funny, touching story about life changes, friendship and first
love.
Josie has lived on her boat, Promise, her whole life. She finds it
easier to walk on deck than she does to walk on land. But Promise
has been condemned, and in turn, Josie is condemned to live on
dry land, in a grotty flat, without her best friend Bella.
Then she meets Leon, a boy from her neighbourhood. He dares Josie
to do something that might mean she can live on a boat again. But
that would mean leaving Leon, just when Josie is getting close
to him...
