Three unlikely heroes in the medieval kingdom of Northumbria who must unite to stop a royal conspiracy. When a mysterious illness befalls the king, Prince Tristan is lured into a dangerous quest, while his younger brother William — neurodivergent and non-verbal — uncovers the plot at home. Teaming with a magical stable girl Alora and her fearless ally Constance, William helps expose a coup and ultimately proves that compassion, not force, is the kingdom’s greatest strength.
