Summary: Harry never expected to find out that Remus had a twin sister; nor did he expect the appearance of his mother's best friend. And he certainly didn't expect the history they, and Sirius, all shared. But perhaps these four links to Harry's parents can help him in his ever-lasting war with Voldemort - and in the process, give him the family he never had. AU OotP, with some canon left intact. NOT a Mary Sue fic.
Summary: What was Sirius thinking as he escaped from Azkaban and made history? One-shot.
