"The Seven and the Ghost. The Moonlark and its Host"
An ancient prophecy from a forgotten source arises once again. It speaks of a world hidden beyond mortal sight, a castle divided by ancient rivalries, and a boy wronged by tale and name whose fate could change everything.
The Giant War, Percy Jackson, Annabeth Chase, Jason Grace, Piper McLean, Frank Zhang, Hazel Levesque, and Nico di Angelo are sent to a place no demigod has ever walked before: Hogwarts School of Witchcraft and Wizardry. Posing as exchange students during Harry Potter's fifth year, their mission seems impossible-find the mysterious boy from the prophecy, help him fulfill his destiny, and somehow unite four houses that can barely stand each other.
But they aren't the only ones answering the call.
From a hidden world of lost cities and dangerous secrets, Sophie Foster, Keefe Sencen, Fitz and Biana Vacker, Dex Dizznee, Tam Song, and Linh Song arrive at Hogwarts with a mission of their own. The Neverseen have vanished without a trace, and the sudden silence is more terrifying than any attack. When clues point toward an alliance with Lord Voldemort's followers, the elves find themselves drawn into a war they never knew existed.
As old enemies gather in the shadows and tensions rise within the castle walls, three worlds collide for the first time.
Demigods. Elves. Wizards.
None of them know the others exist. The worlds were never supposed to collide, but the Fates had other plans.
And somewhere within Hogwarts is the boy they were all sent to find, who could save or doom them all.
This story takes place during the Order of the Phoenix, after the Heroes of Olympus series, and after Lodestar. All characters belong to their respective authors, but the plot, characterization of the characters, and some original characters belong to me.
