Dumbledore's Army and the Ambrosius Chalice

Seth wouldn't have ever thought he would have to deal with the threat of the Dark Lord's return as a first-year. But when he and Jordyn overhear dark whispers in the castle corridor, he soon learns that all people keep secrets — not just the bad guys. Not knowing who to trust, it's up to a band of students to put a stop to the Dark and their plans to resurrect Voldemort once again.
