A kingdom in the future, a girl from the past, and a stained-glass window that can't be found.

Mia Miller just needed a moment to breathe and admire the stained-glass window in the chapel before she had to plaster on a fake smile for her only sister's wedding reception. Her artist's eye drew her to the window but something else entirely made her fall through it. Now she's stuck in a strange land, a different time, mistaken for a princess, and the stained-glass window nowhere to be found.

With Rebels stealing his Kingdom's low food supplies, Prince Liam Dunne agrees to an Engagement to secure better trading routes. When the princess arrives without a shred of luggage or her entourage but plenty of anxiety, his heart has a hard time staying out of it. Princess Amelia challenges what he believes in-in a world where faith is eradicated. But when the truth comes out about her true identity, will he have the courage to live up to his family's legacy?
