"I love this series to pieces and so should you."—Marie Lu, bestselling author of Warcross

This riveting prequel to Rae Carson's award-winning and New York Times–bestselling Girl of Fire and Thorns series introduces readers to Hector before he became the man Queen Elisa fell in love with.

At fifteen years old, Hector is the youngest squire in the most elite military force in the country. And his first day is disastrous. Everyone assumes the only reason he was recruited is his close personal association with King Alejandro, not because he's really earned it.

But Alejandro needs Hector for a secret mission, one that gives him the chance to prove to everyone—including himself—that he is worthy to be a Royal Guard. Hector must break into the ancient Fortress of Wind to retrieve something so important that the kingdom's future depends on it. What Hector finds in the fortress will stretch his bond of friendship with his king near to breaking. And it will prepare him to become the fearsome warrior and lord commander Elisa will never let go.
