Somehow, in some shape and some form, the world of Harry Potter collides with one filled with Greek and Roman gods. Percy, Annabeth, and other campers are tasked with infiltrating Hogwarts and somehow separate the two dimensions, so their lives can go back to normal. Yet things don't exactly go as planned...

Political tension, international strife, and civil conflicts, and an encroaching danger looming in the horizon. In the time of need, they must choose their loyalty, and unite, or else the world will fall into darkness. Yet even as the rays of the sun emerge from the clouds, the true danger is yet to come.
