Apollo's Song Two-Part Edition 1

Apollo's Song follows the tragic journey of Shogo, a young man whose abusive childhood has instilled in him a loathing for love so profound he finds himself compelled to acts of violence when he is witness to any act of intimacy or affection whether by human or beast. His hate is such that the gods intervene, cursing Shogo to experience love throughout the ages, only to ultimately to have it ripped from his heart every time. From the Nazi atrocities of World War II to a dystopian future of human cloning, Shogo loses his heart, and, in so doing, heals the psychological scars of his childhood hatred.
