For years, myths and legends about the Underworld revolved around the earth. The darkest, most horrible place you could ever think of. But they were just myths and legends, carvings of ancient stories. No, Hades -God of the Underworld- did not exist. No, there wasn't anyone who could rule a place like that. No, a mere person could not radiate fear and darkness. No, millions of souls certainly would never kneel down before just one person. That's what every single one of them believed in. Unless, he was an immortal of course. Like Hayden Stone. Ava Bensen, like every other sane human, did not believe in such stuff. Yes, she had a perfect life -or at least, that's what her parents wanted her to believe in. Rich parents. Beautiful looks. Caring best friends. Everything was perfect. But sometimes, people forget how perfection is just a fancy form of fear. Fear, that kills hundreds of people each day. Fear, that everyone despised and stayed away from. Fear, that could take form of the Furies, the deadliest creatures of the Underworld. Ava didn't know that. She didn't know what was coming her way. Not until she died. For real.
