When 16 year old Cyrena Masten already knew she was adopted. The real kicker was when she found about gods, monsters, and a half-brother that scared her to death. No pun intended. Now they have to get to Ogygia to find an item that could possibly make or break the world. Will Cyrena and her brother along with a few friends be able to save the world by defeating the literal darkness? And, of course, by a few friends, I mean Percy Jackson, Annabeth Chase, and Repair Boy.
