The Life of Lillian Black

Lillian is Sirius Black's granddaughter, and is chosen in a dangerous prophecy. She and her friends, Albus Potter, Teddy Lupin, and Rose Weasly become the second generation of marauders at Hogwarts, after the original. Lillian risks her life to save the wizarding world. (Mad-Eye and Snape are alive.) Lots of credit given to Shadowcat300 on chickensmoothie for helping me with this.
