Dumbledore's Army and the Ambrosius Chalice

Learning magic is difficult enough without having to worry about a race to find a legendary artefact. All Seth has ever wanted was to go to Hogwarts, make friends, and rise to the top of his class. But when he and his best friend Jordyn overhear a whispered conversation about the return of Lord Voldemort, all ability to focus on his studies goes out the window faster than a Zouwo.

The Dark Forces have barely survived since You-Know-Who was defeated, but now they're stirring once again. Someone at Hogwarts is on the hunt for an artefact hidden within the castle that is rumoured to have the power to resurrect the Dark Lord. Not knowing who they can trust, it's up to a small band of students to prevent the Ambrosius Chalice from falling into the wrong hands. But with mysterious clues, dodgy teachers, and bothersome classmates, will they be able to find it in time?
