When Emily Kingsley arrives at the church, late and sad, for her Great Aunt Mary's funeral, she has no idea that her life is about to change completely. Still grieving for her broken relationship with the vain, mean and unfaithful Ted, and trying to come to terms with the cracks which seem to be appearing in her parents' marriage, she sobs her heart out in the church. At the wake afterwards, however, she and her cousin Clemmie are told that Mary has appointed them executors of part of her Will. They are to transport her ashes to Mali, in western Africa and her final resting place is to be Timadjlalen, in the Saharan desert. And so begins Emily and Clemmie's adventure - a journey that will be the most important of their lives.
