Serpendipity

Odette has lived a life that, on pen and paper, would sound fascinating.

Travelling monthly with her Auror parents, hiding out with some of the Resistance's most elite whilst her parents gathered whatever traces and word of Grindelwald that they could.
Except, Odette's life consisted mostly of being stuffed away in grand, dusty rooms with her brother, using the light from exhausted candles to homeschool themselves in witchcraft.

Finally, by a fortunate stroke of serendipity, her aunts settling down in London, not far from King's Cross, Odette's parents finally gave in, placing their children under the permanent care of their aunts.
Joining Hogwarts in hopes of a stable life as she waited out the rest of her school days, the immense danger her parents sought to reveal and protect her from was no longer distant.

It waits for her within the castle's walls.
