When Sophie is suddenly orphaned at the age of six, she is taken from her parents' tea plantation, the only home she has ever known, to be raised halfway across the world in Scotland. As the years pass and her exotic childhood becomes a distant memory, adventurous Sophie finds refuge in her friendship with her kind, shy cousin, Tilly. It is no surprise when the girls follow each other to India to embark on new adventures, new lives and new loves. But the reality of 1920s India is far removed from their dream: the jungles are too humid and the breathtaking tea gardens too remote. And amongst the stifling beauty, intrigue abounds; while Sophie struggles with affairs of the heart, Tilly, alone in a difficult world, delves into the mystery of Sophie's parents' deaths. As the past begins to darken their friendship, will long-held secrets shatter everything they've ever striven for?
