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. Clemmie, fanciful and rootless, is thrilled at the chance of adventure. Emily is not. With immense reluctance, she agrees to travel to Mali, and find Timadjlalen, a place in the desert that no one has ever heard of. Why Mary chose it as her final resting place, she cannot imagine; and the though to a hot, pointless trip is almost too much to bear. But once Emily and Clemmic set foot on the Saharan sand, and begin to uncover Mary's sixty-year-old secret, they come to understand why them ust complete her journey.
