Substitute Bride for the World Serpent

In the Nine Realms, half-elf Princess Leora is abused for her impure blood. A masked man saves her; she heals him with her body and gets pregnant. Yet neither knows the other.

Her father forces her to marry Jorvin, the World Serpent. But when she arrives to wed him, she's found pregnant. Believing she betrayed him, Jorvin agrees to let Asgard execute her—until the child in her belly calls him "Dad"!
