In that moment she realises that Anna Swan was a woman of many secrets.

Only by travelling to Norway and discovering the story of four brave young women whose lives were forever changed by the occupation of their tiny islands, can Maggie uncover the shocking truth about her family - and finally unlock the mystery of the glass key...
