To everyone else at Hogwarts School of Witchcraft and Wizardry, having Harry Potter as your Defense Against the Dark Arts professor was a dream come true. For those students whose surnames were Potter, Weasley, Lupin, Malfoy, and Dursley, it was anything but. At home, Harry was everyone’s favorite; full of amazing stories and always ready to play or fly. At Hogwarts, he was just  professor . Not even his own children were allowed to call him "dad." Coming into their first year, Ellie and James were quite certain Defense Against the Dark Arts was going to be a breeze.
