Gussie is a twelve year old girl from St. Ives in Cornwall. She is passionate about learning, wildlife, poetry, literature, and she wants to be a photographer when she grows up.
But her dreams were put on hold as she struggled with a serious heart condition.
Now she has got what she needed: a heart and lung transplant.
But it isn't working out quite the way she thought. Firstly she has to leave her beloved Cornwall to live in London and in the months following her operation she is unable to do very much except read and adopt a stray kitten, but she could do that when she was sick.
She craves adventure and experience beyond her four walls, until, that is, she hits upon a plan - she is going to get her divorced parents to fall in love again.
It's not going to be easy, her mum is still dating her doctor boyfriend and despises Gussie's father, who happens to be living with his new girlfriend - the Snow Queen.
But Gussie is a determined girl and there is only one thing that could stop her now.
