Wealthy and influential beyond measure, for centuries La Famille Delacour has subtly influenced events in their favor, and Hermione Granger's life is irrevocably changed when she wanders into Diagon alley at age eight and draws their attention. With the backing of a powerful French pureblood family, Hermione is sucked into a web of mysteries and lies as she enters Hogwarts.

At age 8 Hermione Rosier is recruited to be a Field Agent of the Department of Mysteries. At age 11 she is given her first mission: Attend Hogwarts and befriend Harry Potter the Boy-Who-Lived. She takes on the name Hermione Granger and under the guise of a know-it-all, muggleborn student, Hogwarts brings the promise of adventure and friendship, if she doesn't blow her cover first
