Violet invents her 'Theory of Leaving Small Things' (when you leave something small in a nice place, so a tiny bit of you gets to stay too).

Then there are two lots of special news: Mum and Vincent are getting married, and they'll all be moving to a new house.

Violet is excited about the wedding part (she will wear a dress with fairy wings) but not so keen on the moving house: brother Dylan is not keen on any of it.

Whilst everyone pitches in on the preparations, he pitches his tent right in the middle of the wedding party.

Can Violet help Dylan leave part of himself behind while they all move on together?
