I had read Lucy Christopher's "Stolen" and was eager to read her next book. This did not disappoint. The story is rich with well-developed characters about whom you come to care deeply. Isla, the main character, is a young teen who shares with her dad an intense interest in birding, and in watching wild whooper swans as they migrate into England for the winter. She and her dad are following a flock of swans as they migrate in, when he suffers a heart attack. As she and her family anxiously hover in the hospital while her father receives treatment, she meets a boy, a young cancer patient. The story follows several threads, always with Isla as the narrator. One thread is about the way her mother, brother and Isla pull together around her very ill father. This is a warm, caring family, and the ways in which they quarreled, yet supported each other rang very true. There is another thread about Isla's grandfather, her father's father, who has an intense fear and dislike of hospitals after having lost his wife to an infection she picked up while being treated in one. There is a thread about the swans, who are having more and more difficulty finding places to winter as urbanization takes over their old habitats. Isla and her father had shared this concern, and she takes on the mantle of care while he is ill, sharing snippets of her observations with him to cheer him toward recovery. Finally, there is a thread about a budding romance Isla has with a boy awaiting a bone marrow transplant. They watch a lone swan on a lake they can see from his hospital window, and devise a plan to help the swan rejoin her flock. In all of this, these stories of life in its many permutations, there is a binding love, a transcendent human compassion and spiritual bonding of one life to another. As Isla tells her art class, when making a presentation about flight and the flight of swans in particular, the swans need each other to migrate. They need each other to be carried through the currents of air, through darkness and the unknown. And so do we need each other, the support of other life, in this world. This is just a beautiful, haunting book. Ms. Christopher is truly talented and I look forward to reading more from her.
