Bellatrix's Daughter

Bella is the kind of child you hear about who's left on a doorstep. But Bella's not a regular child -- at age fifteen, she gets a letter to Hogwarts School of Witchcraft and Wizardry. There she might learn about her family, who she really is, and how important she is . . . oh, and help Harry Potter retrieve his prophecy at the Ministry of Magic, where she meets someone interesting . . .
