A Harry Potter Collection of Fairy Tales

This is a collection of Harry Potter oneshots/drabbles, written for the Diagon Alley II Fairy Tales Challenge. Summary and pairings/characters will change with each chapter posted. Chapter 1: Tonks is a good liar, but Remus always knows when she does. This isn't something she's used to, and when her cousin Sirius is added into the mix, who knows what will happen?
