Scorpius and Rose haven't been in touch for two years, until Rose finds a special mirror while looking for some papers. I realize my summaries are always like one sentence long, but I honestly can't think of anything else to say.

Scorpius doesn't realize what he had until he looses it.

There's a barrier of prejudice and hatred that separates them.

Vaguely follows the plot of Romeo and Juliet. Scorpius and Rose meet at a masquerade ball at the Ministry and, despite their parents warnings fall in love. This can't end well.

Scorpius and Rose have some loose ends.

Scorpius wants to know who Rose likes.

I, Rose Weasley, am sick. There's no other possible explanation for it. Rose's cousins come up with a plan to make her realize the true cause of her strange feelings.

This is very similar to my Enchanted Parchment story. Rose, Scorpius and Albus pass notes during History of Magic, and make confessions wouldn't make if not under the influence of magic.

Lily and the Marauders exchange notes and eventually discover a few things about each other.

I haven't figured out the entire story yet, but so far; Albus doesn't like his knew glasses, so he, Rose, and Scorpius try to destroy them.
