After the tragic death of his mother, eleven year old Will is sent to temporarily stay with his uncle in the mountains. After years trapped in a high-rise flat, with only birds for company, Will doesn’t know how he’ll survive a place like this, but he soon finds solace in the woods, when he’s surrounded by birdsong. With his new friend Omar – a refugee from Afghanistan – Will discovers an osprey nest, with two small chicks inside. He forms an unbreakable bond with the birds, especially the smallest chick, who they name Whitetip. But when tragedy almost strikes again one stormy night, and Whitetip is knocked out of the nest – breaking a wing, Will is determined to save her. Smuggling her down from the mountain, he finds a way to keep her alive. As Will helps Whitetip to grow and to heal, he finds a strength inside himself that he never knew he had.
