I Married My Sister's Dragon King

The night before her Dragon Bond Ceremony, Elara catches her fiancé in bed with her twin sister. Even worse, she learns she was never his true choice—only a backup meant to die in her sister's place. Forced into a deadly bond with the feared Silver Dragon King, Elara expects death. Instead, she awakens the legendary power of the Moonborn, becoming the only person who can cure Dragon Madness. As the truth comes to light, her faithless fiancé realizes she was the one who saved him all those years ago. But his regret comes too late. Standing beside Elara is the powerful Dragon King who has loved her since childhood—and this time, she won't choose the man who betrayed her.
