The begining

three demigods will travel the world in search of a book that contains the prophecy that could save the world. The third one is a mystery until they are sent to seek him. They have to travel to Hogwarts school of witch craft and wizardry in Scotland. They are very confused but all is answered eventually, but will they find what they need and save the world or will his be the end of the world as they know it.

Disclaimer I do not own anyone from the Percy Jackson or harry potter series. And that includes the heros of olympus.
