When Sara opened the cardboard box left at her front door, she had no idea what affect the Peregrine Falcon it contained, was to have on her life. She had cared for many birds in the Wild Bird Hospital she ran in Mid Wales, but none had affected her in this strange way, none had been so close.
Taking her courage in her hands, she contacts ex-lover, Gabriel, who helped her heal the birds when they were together with great skill. He doesn't have an answer for her, but she knows the falcon, Mistral, wants something of her and the journey it leads her on takes her across the sea to British Columbia, led on by the dreams.
On the way she makes new friends, also affected by the birds - amongst them a Haida Indian, who holds the key to the mystery. Through danger and hardship, she eventually finds the answer and her life is changed forever.
