Can a mother's secret past provide the answers for a daughter's future? Celebrity photographer Grace Buchanan has always known that, one day, she'd swap her manic day job for the peace and quiet of her beloved childhood cottage, St Christopher's - she just didn't expect it to be so soon. At the reading of her mother's will, she's shocked to learn that she hardly knew Rosamund at all, and that inheriting St Christopher's hangs on one big - and very inconvenient - condition: Grace must drop everything for two weeks and travel the country with a mysterious stranger - war-weary Royal Marine, Alasdair Finn. Caught in a brief but perfect moment in time, Grace and Alasdair walk in Rosamund's footsteps and read her letters at each breathtaking new place. As Grace slowly uncovers the truth about her mother's incredible life story, Alasdair and Grace can't help but question their own futures. Will Rosamund's madcap scheme go to plan or will events take an unexpected turn? An emotional, fun-filled and adventurous journey of a lifetime.
