I Took a Substitute Bride's Place to Bring Luck to a Sickly Groom, and Now the Dragon Dotes on Me

Shen Xiruo, an adopted daughter of the Shen family, is forced to take another bride’s place and marry the frail young heir everyone avoids, in hopes that the wedding will improve his health. She expects to become a widow in all but name, only to discover that her husband is a dragon descendant who has been pretending to be sick. Even more astonishing, she is no ordinary orphan but a princess lost to the dragon clan. A marriage contract made in another bride’s stead draws her into a thousand-year-old feud within the dragon clan and a quest to find four dragon pearls. It also sets her on a fated romance across species with the supposedly sickly young heir.
