The Dragon Skin Journal

James Sirius Potter doesn't know too much about his grandfather and what all the Marauders got up to before their untimely death. He never asks his father in fear of bringing back sad memories. He decides to keep his curiosity to himself, that is until he finds an old journal hiding under his bed in the Gryffindor tower. He opens the journal and discovers that is written by none other than Peter Pettigrew, the man who sold his grandparents out to Lord Voldemort. He decides to read it, and shows his siblings the wonderful memories of their grandparents and their best friends. He even learns some things he wishes he hasn't.
