After three failed marriages, Archduke Theo de Phoenix has long accepted that love simply isn't in the cards for him. After all, who could love a war-hardened monster like him? So when his fourth bride arrives, he greets her covered in blood, gives her a shabby attic for a room, and keeps his distance. Surely, this one will run too. But Yuelina is not like the others. To Theo's disbelief, she welcomes his presence and fills his cold world with warmth and light. As the walls around his heart begin to thaw, will Theo finally allow himself to love?
