Invited to join him on a trip to Russia, Lydia jumps at the chance to discover more about the past she finds increasingly difficult to remember. But when reality sets in, is all as it seems? With the Second World War looming, Lydia’s situation becomes desperate. Will she ever find a place to finally think of as home?
