Elin has the perfect life. A successful photographer, she lives in New York with her husband Sam and their seventeen-year-old daughter, Alice.
But something has always been missing...
When Elin receives a letter from her childhood friend Fredrik on the Swedish island of Gotland, memories come flooding back: of a past she has tried to forget, and a terrible secret she has shared with nobody - a secret that made her flee the island, and never return.
Torn between past and present and afraid the truth will destroy her family, Elin sets out on a journey to another continent, but also to another time and another life.
