When Worlds Collide by jenny b
Rated: 6th-7th Years [Reviews - 254]
Summary: 
Rose was a Weasley. She never gave Scorpius Malfoy a second glance. They were sworn enemies, even though they’d barely even spoken to each other. But sometimes all it takes for love to blossom is a Potions lesson, a few snide remarks and a dropped book.
Two people. Two entirely different worlds that are suddenly intertwined.
