Sir Caelan Alaric's orders were simple: watch the violet-eyed princess, not protect her. Because the last time a star-born heir came of age, Eldale burned.

Princess Elira hears whispers in the shadows no one else can hear. When a shade-dragon calls her by name and assassins hunt her in the night, she realizes the crown's protection is really a prison - and her knight's sword might be meant for her throat.

As an ancient prophecy unfolds, Caelan must choose between his oath and the woman who ignites forbidden magic in his veins. Elira must decide whether to surrender her power or unleash the storm that could destroy them all.
