When a brain tumour takes the life of Becky Livingston's twenty-three-year-old daughter Rachel, her life makes an unconventional turn. Rachel, an avid traveller, had one wish: to keep exploring the world.

So, for twenty-six months Livingston travels - untethered and alone - to Italy, Spain, Switzerland, Australia, India, England, Ireland and North America, coast to coast. In her suitcase: Rachel's ashes, heavy but compact. As she gradually merges her daughter's remains with the elements, Livingston learns how to forge a new sense of belonging in an unfamiliar world.
