Hecate's Curse: A Harry Potter and Percy Jackson Crossover

"Harry, this blade seems magical. I need to bring it back to the hotel and reference my copy of 'A Study of Ancient Magical Weapons.' I'll see for myself if it's something dangerous."

When Harry, Ron, and Hermione are in New York City, Hermione finds a mysterious dagger in an alleyway, covered in a strange yellow dust.

Meanwhile, back at Camp Half-Blood, Lacy from the Aphrodite cabin has gone missing. But something isn't normal about her disappearance. When Percy, Annabeth, and Piper go on a quest to find her, they find something even more mysterious- wizards.

Something is very wrong. These two worlds of magic and gods were never supposed to collide. But now that they have, what will become of their inhabitants? The cause of all this lies in one goddess... and she may just be deadly.
