The demigod world is in chaos. Everyone is training to become heroes, but no one wants to step up and save the world from Ouranos' rising force - or, no one's allowed to, at least.
Lily Jackson is anxious to fight. She knows that her destiny lies within the battle, but can she step up and take the lead?
Ethan Jackson is living a life in the past. Ever since his best friend Silena died, he's been distant and broken. Can he put the past behind him?
But their friends are here to help. Maria, Emily, Hayley, Noah, Mia and Thomas are here to fight this war alongside Lily and Ethan, and they're prepared to go all out.
