Growing up, the Anderson sisters were close, even though they were different. Susie, the wild one, wanted an adventurous life while Mills followed a safer path.

When Susie dies suddenly from a fall when hanging a string of lights for her fortieth birthday party, Mills is grief-stricken, even though they had drifted apart. Then Mills receives a bundle of mysterious letters from her sister to be read in the case of her death. Each letter instructs her to visit a place special to Susie, both to spread her ashes but also to uncover some truths Susie has long kept hidden from her family. Truths that seem to date back to one golden summer in an idyllic French coastal town, where a dark and shocking event was the beginning of an unravelling thread. A thread that leads both to Mills' present and her mother Margaret's past.

What choices connect the past to the present? What family secrets will surface and change the future?

In this twisty, evocative mystery, Jane Cockram flips the looking glass to reveal the lines of deception and love, truth and regret that run through families.
