One lost suitcase. Two strangers. And a notebook that will change lives.

For almost fifty years, sisters Dolly and Greta have lived together - getting each other through the good times and the bad.

Except this year, Greta isn't there and Dolly is feeling lost and alone. In memory of her sister, Dolly heads to the lost luggage auction where she and Greta go each Christmas. But her bid reveals a gift she never imagined.

Amongst the clothes is the notebook of a reclusive woman who has hardly been outside for an entire year, but who isn't ready to give up on life. The notebook's contents resonate with Dolly. With the support of her neighbours, retired Leroy and eleven year old Flo, Dolly decides to take on the year of firsts Phoebe had planned.

But, can you have a year of firsts when you're seventy-two? And is Dolly ready to discover the notebook's secrets, or are some secrets better left lost at the airport?
