Living in the Underworld takes some getting used to, but finding out you aren't what you thought you were is a completely different story. Seraphina could live with the fact that her dad was Hades, but when the Gods bring her to Olympus and tell her that she is actually a demititan, she feels as if her world has shattered. Not only that, but there are more of her kind, and the Gods are in a race against Hades to find the others before he uses the demititans' powers against Olympus. With the help of her friends, Seraphina must struggle through living in the mortal world and finding the others before her so-called father. But what she finds might just pull her over the edge completely.
