Sent to the enemy kingdom of Rihtlond to marry the high dane’s son, a rebellious young woman is expected to act as a spy, armed only with a coded journal, a quill and her intelligence. Her family regards the dangerous mission as expendable service, but her life changes when she falls for the kingdom’s weaponmaster. As he helps her understand his people, she uncovers hidden magic, a dragon concealed in plain sight and truths that challenge everything she has been taught. With war approaching and alliances collapsing, she must choose between the family that sent her away and the people she has come to love, even if protecting them makes her a traitor.
