The Sneeze

Meet Kierandus Lestrange. Raised by his Aunt Tonks in secret, he has no idea that his parents are the two most dangerous Death Eaters in the world. But once the Ministry finds him out, his life changes drastically. Placed in Hogwarts, he's cousin to Draco, loathed by Harry, and feared by almost everyone else. The only one he can trust is Severus Snape, but little good that does him when mummy and daddy come visiting. Set after OotP, well researched, witty, and full of drama.

You've never seen Fred Weasley like this before. His newly erratic behavior leaves his twin in the dust, and soon the trio realize just how deep and how dangerous these changes truly are. But can they stop Fred's descent before his newest mischief turns deadly? Current HP timeline/many characters involved/realistic.
