He'd finally found them. Tom Riddle's heir. A boy no older than seventeen, with hair of a raven night and eyes of a churning ocean. The wizened old man closed the weathered book. The Fates had been kind enough to let him in on this secret, one he fully intended to use to his advantage. The boy must not fall into the wrong hands. It was time to pay an old student a visit. ~ DISCLAIMER: I do not own either the Harry Potter characters nor the Percy Jackson characters used in this story. None of the characters are mine more shall I pretend they are, this is but a work of fiction. Characters belong to their respective owners (JK Rowling and Rick Riordan). The plot however, is my own. ~ Edited by BookwormMDCCCXIII
