"A Star in the Shadows"

Prompt: Cassiopeia “Cass” Selene Malfoy is born the younger twin to Draco Malfoy. When she’s only a month old, she’s stolen away and disguised with blood magic — her identity hidden. She’s left with James and Lily Potter under the name Harriet Potter. After the Potters’ deaths, she grows up with the Dursleys, where her bubbly, dramatic personality clashes with their drab cruelty. She survives with charm and sharp wit, often at Dudley’s expense.
