The Serpent and the Eagle

Cassia Ollivander is living up to her Ravenclaw family's legacy. She excels in all of her classes, Charms is her best class, Transfiguration comes easily to her, and Arithmancy is a breeze. Potions, on the other hand, is a completely different story. From the very first day she set foot in Professor Snape's dungeon, her potions have ended up worse than Neville Longbottom's, or so Professor Snape tells her. In her fifth year, her OWLs are suddenly around the corner and she's panicking. Thank goodness Professor Slughorn is so much more forgiving than Professor Snape, because when he realizes she needs extra help, he assigns her to a Prefect who had achieved an Outstanding in his Potions OWL the year before. Draco Malfoy isn't much of a teacher, or someone to be friends with, for that matter, but there's something about him that draws Cassia in.
