They were never meant for happily-ever-after.
They fell in love anyway. She thought he was dead.
Four years after the disappearance of her beloved prince, Lady Allette Rittey returns to the fae realm to find Prince Senan very much alive—and on the verge of marrying a bloody princess.

Desperate for answers, Allette poses as a servant to gain access to his castle. But the wedding bells are ringing, and she’s running out of time before she loses him forever.

Prince Senan Vale has problems.
A lot of them.
Most pressing, an arranged marriage not to the woman he was meant for, but the princess of a neighboring kingdom.
When the king refuses to call off the engagement, Senan loses all hope.
Then his long-lost love returns from the grave.

Senan and Allette learn the truth of what kept them apart, discovering they have been betrayed by those closest to them.

The only way to be together is to flee the kingdom.
But first they must escape a castle full of traitors.
