Harry Potter: King's Cross

This is her final year in Britain.

After returning home, she expects the usual: a job, blind dates, marriage, children. Everything is arranged down to the last detail. It should be a good life, but she feels as if she can already see the path from youth to old age stretching to the end.

After doing the first outrageous thing of her life, she discovers the secret hidden deep within this world: magic isn't a fantasy, and J.K. Rowling is a witch. This is our world, and it's also a world of magic. This is a miraculous encounter, and a turning point in fate.

Notes: 1. The heroine is a Muggle.

2. The hero is a wizard.

3. This is set in the real world, with Warner Bros., Universal Studios, Daniel, Emma, Rupert, and Tom (though I'm not sure whether they'll appear in the story). The setting is fantastical, and although the blurb sounds dramatic, as if the world needs saving, this is actually a low-key love story.

4. Even if life-changing love stories are melodramatic, that doesn't stop them from being classics.

Theme: A way to make Harry Potter make sense in the real world.
