An 18-year-old girl wakes up in the private gardens of a royal estate with no memory of how she got there or any knowledge of the world around her. She is discovered by Crown Prince Aidan Ashford, who suspects she may be a spy but quickly realizes she doesn’t understand court life at all. Instead of reporting her, he hides her. As he faces pressure to choose a politically strategic bride, this mysterious girl becomes an unpredictable presence in his carefully controlled life, creating tension between duty and curiosity.
