Part 3 of The Arithmancer Series. Hermione won the war, but her career as the world's greatest arithmancer is just beginning. Now, she has places to go, spells to invent, and a family to start. Oh, and a whole lot of dementors to kill.

(Complete) The love of the Minister's life disappeared just before the end of the First Wizarding War. When he finds her again, he can hardly trust his sanity. His first action as the new Minister for Magic is to break at least a dozen international laws to bring her home. Hermione soon finds herself in the early 70s surrounded by future followers of the Dark Lord.

Hermione grows up as a maths whiz instead of a bookworm and tests into Arithmancy in her first year. With the help of her friends and Professor Vector, she puts her superhuman spellcrafting skills to good use in the fight against Voldemort. Years 1-4. Sequel posted.
