Katherine, the daughter of Hades, the god of the underworld, and Demeter, the daughter of Zeus, the king of gods, are best friends. They've been through hell and back together, but this was something like no other. Their families have had a rivalry for ever since they remember, but they never let it interfere in their lives. As a new classmate named Skyler comes and an important secret is revealed, these girls realize too lately that they are more special than they realize. A special power, bond, connects these girls in a special way. A certain organization finds out and is on the lookout for these three girls, trying everything they can to reach through to them and make them pay. Will these girls stay together through thin and thick? Why are those people after them? Is Katherine who she really thinks she is? Secrets are revealed as bonds grow and trouble rises.
