The Gatekeeper's Son

Delivered stillborn, Sooshay-Chan was unexpectedly brought back to life when his mother, Mi, summoned the previous Gatekeeper, Kazuko, to formally accept her role as Guardian of the Gateway. Because he demonstrates knowledge and skills no child should possess, his family suspects the boy has been reborn with the soul of his grandfather. Mi is the only one who knows that her father's spirit has traded places with the spirit of her unborn son in the Realms Beyond. When warned by her sister named for the virtue of Justice that she must send her father's spirit back, or the ancient Goddess of Death will escape into the realm of living, she is torn.

Never before has a Guardian had a living child; Sooshay-Chan is unique in all the history of the land. How can she save her son without destroying the world?
What choice does she have?
