Crown Prince Archer Briarthorne has spent his entire life devoted to duty, honor, and the crown he is destined to inherit. So when his parents arrange his engagement to Princess Vanessa of Valoria, Archer accepts the match without question. Until he meets her guard. Silia Chavez, the only female knight in Valoria's royal guard, is everything Archer should not want—fierce, disciplined, and utterly unattainable. Sworn to protect his fiancée, she is always near enough to unravel him, yet forever out of reach. Every glance becomes dangerous. Every touch becomes unbearable. And for the first time in his life, Archer wants something more than the crown. He wants her. But in a kingdom built on duty, loving the wrong person may cost him everything.
