For centuries, Hogwarts has celebrated lions and feared serpents. You’re used to the whispers that follow green-and-silver robes through the corridors. Slytherins are arrogant. Manipulative. Dangerous. At least, that’s what everyone says. When a mysterious force begins attacking students and threatening Hogwarts itself, the castle’s so-called heroes are left chasing dead ends. Refusing to sit back and watch her house take the blame yet again, you launch your own investigation alongside a group of ambitious, fiercely loyal Slytherins. The deeper they dig, the more they realize that Hogwarts was built on secrets—and some of those secrets were deliberately hidden to make Slytherin House the villain of history. In a battle between truth and tradition, you will discover that being a hero doesn’t always mean wearing red and gold. Sometimes heroes wear green.
