This novel intertwines the lives of two characters: James More, a British spy captured by jihadist fighters in Somalia, and Danielle Flinders, a biomathematician exploring the depths of the ocean. As they face their respective forms of isolation and danger, their thoughts drift to a Christmas past spent together in a French hotel, where they fell in love. Through their separate yet parallel experiences, the narrative explores themes of love, the vastness of the human spirit, and the profound connections between the ocean's depths and the most remote desert lands, highlighting the fragility and depth of human existence in the face of the natural world's immensity.
