Quest of the Half Gods

Apollo confused. He feels as though he is without purpose. After facing trials that changed his view on life forever, he feels trapped in a position that he no longer wants or has a reason to stay in. He wants to find something worth doing again but doesn't know how.
Galatea is angry. She had her entire life planned out and was very happy with it until an algae-covered idiot named Percy Jackson took it all away from her. Now, she's been forced back into a life she didn't want and one that could have deadly consequences for the people around her.
When Apollo and Galatea arrive at Camp Half-blood on the same day, they don't expect to be thrown headfirst into a quest that could mean the end of everything, but that's what happened. Now they have the weight of the entire world on their shoulders as they race to save the Olympians before the New Gods can destroy everything that everyone knows and loves and throw the world into chaos.
