theory of the next book PERSADES (Read the description)
DRAMA: Ares asks for Persephone's hand in marriage, and she rejects him. Her instincts tell her he's not the right man. Hera is angry with her, and so is Demeter (necessary for the plot).
REVENGE: When Persephone falls in love with Hades, they plan their kidnapping together XD. Zeus is nowhere to be seen. Demeter is offended and asks Hera and Aphrodite for help (she also gets involved, it's necessary). They PUNISH Persephone by making her sterile:
Hera: legitimate fertility: no legitimate offspring
Aphrodite: sexual fertility: no passion
Demeter: fertility without abundance: death
Persephone, Mary Sue, defeats all three, proclaims herself the most beautiful (by the way, she wasn't; Hera was the greatest immortal beauty, cry no more XD), and becomes the most feared queen. Aphrodite is back for a second round: Adonis, like Persephone and Hades, was cursed to have no offspring. They adopted Adonis, and the evil Aphrodite wanted him for herself. Aphrodite has like 7 biological children, leave Adonis alone for Hades and Persephone. OBVIOUSLY ZEUS IS ALSO THE BAD GUY HERE.
Oh, I forgot, they aren't uncle and niece married.
