A Muggle-born Magic (гет)

Regency-era AU. Physician's daughter Hermione Granger finds herself in need of a way to pay off her father's debts after his death. Draco Malfoy, retired from the politics of the Isolationists, a group of pure-bloods bent on separating 'true' magic from lesser folk, finds himself in need of a tutor for his son, Scorpius, who appears to be incapable of magic and must learn to survive in a world without it. Draco also needs a wife and mother for Scorpius, to satisfy a promise to his unwell father. After she saves his son from an attack by Isolationists, Draco hires the Muggle-born Miss Granger for the former, and after a riot in Vauxhall Gardens and a scandalous discovery made by his mother, weds that selfsame Muggle-born for the latter. While making the best of her marriage of (in)convenience, Hermione discovers that Scorpius' history of wild imaginings and dreams is more than just imagination. As she attempts to teach him about magical abilities no one expected he would ever have, she and Draco work together to raise Scorpius and learn to trust each other.
