Marlene Potter, the youngest daughter of Lily and James Potter, is given a space at Hogwarts by Albus Dumbledore himself. There she meets her long lost brother, and friends who would soon become family. When she's sorted into Slytherin, that solidifies her new friendship with Pansy Parkinson, Draco Malfoy, Mattheo Potter and Theodore Nott. This is a long slow burn fic about a fan made character and her extremely relationship with a certain Slytherin, along with her adventures at Hogwarts, being a prankster, that is.
