Hera (Olympians, Bk. 3)

There's only one thing Zeus, the King of the Gods, is afraid of. It isn't the many-headed Hydra, or the towering Gigantes. It isn't his powerful, jealous brother Poseidon, the god of the seas. Monsters, gods, Titans - none of them make the mighty Zeus blink an eye. The only thing Zeus fears is his wife: Hera. Goddess of the air, the sky, and the heavens, patroness of the cunning Jason, and scourge of the mighty Heracles, Hera rivals Zeus in power - and surpasses him in wrath.
