Young Queen Blanca embarks on a long journey after receiving a mysterious message carried by a homing pigeon.
Together with the knight apprentices Milian and Cedricus, she rides from the Mountain Country to the distant Plains
- only to discover that the message was a trap.
Behind the deceit stand Prince Astor and the court marshal Gorm. Astor, descended from the ancient Stone Giants, hungers for both power and the giants' long-lost gold. As Blanca and her friends uncover ancient clues - a carved inscription, a faded map, and a secret kept by the Signseer in the Tall Lighthouse - their search draws them deep into a web of mystery and adventure.
In a parallel story, a woman who has lost her memory wanders along a lonely shore. Through dreams, her past slowly returns - until she finally discovers who she is and how her fate is intertwined with the others'.
