My Eternal Damnation

Eight-year-old Elena unknowingly makes a deal with the devil herself. Five years later, Lucifer's end of the bargain is up, and it's time for Elena to hold up her end. What's going to happen to poor Elena? Can she save herself before it's too late? Or does she have no choice but to serve her contracted five human years (500 hell years) in hell...and as one of the devil's personal slaves nonetheless.
