One

Effie Granger is a loner. While her twin sister, Hermione, excels in her classes and befriends Harry Potter, Effie remains in the dark, her closest friend being her diary. One day, her diary goes missing. She discovers it was taken by the George and Fred Weasley, who read every page of it. Soon after, they take a sudden and strange interest in her. But why her? And why are they so intent on befriending her? And why, for the love of Dumbledore, won't Malfoy leave her be?
