UP FOR ADOPTION! What will happen when Harry's unknown sister comes to Hogwarts? Will they all survive or die along the way? Hi this is my first book so please don't judge. Hope you like

Hi okay so Unless Vernon Dursley is a wizard then I do not own Harry Potter, (I have made up a few characters though) Gwendolyn Audrey Rogers is an a normal girl when suddenly magic enters her life, she heads to Hogwarts, makes friends, and for most of the year is a normal witch, with an annoying James Potter tagging along for the ride. But what will happen when stray Death Eaters turn up with Grayback and attacks on full moon? Will they make it? Will Gwen's life ever be the same again? Best rank: 2nd in #NextGenHarryPotter
