Chapter 1: A New Son of Hades
Petunia was reading a letter from Narcissa when her mother came to visit. The summer had been beyond strange, with both she and Lily having to go to some shrink to talk about things. She was surprised that her mother was here, since she hadn't come around in a couple of months.
"Is there something wrong?" Petunia asked her.
She usually came when something was wrong.
"Lord Zeus has just discovered that Hades broke his oath."
Petunia groaned, fearing who child Hades sired.
"And who is it?" Petunia asked her.
"Severus Snape," she answered and Petunia almost passed out in shock.
She told Lily this after her mother had left. Lily was shocked that Severus was a demigod and a son of Hades. Petunia had told her about the oath that Poseidon, Hades, and Zeus had made after the Second World War, the prophecy, and the trouble that those children could cause. One thing was certain; this wasn't going to be a normal year.
