GUARD THE PRINCESS. SAVE THE KINGDOM. STAY ALIVE.Princess Talianna has gotten used to being invisible. As the only child of the royal line, she swears to become the best possible ruler for her people-even if it means no one will ever see the girl behind the crown. When fate reunites her with the knight who was once her best friend, she must hold to her promise and leave the dreams of childhood behind.Sir Gavin of Andel has never forgotten the princess with a smile as brilliant as the sun. When he's assigned to guard her after being separated for ten years, he swears to protect her with his life against all enemies-an oath that may prove as deadly in success as it would in failure. They're bound to their oaths, but fulfilling them may cause their own hearts to break.
