Auror Potter and the Master of Masquerade

For nineteen years, Harry Potter's scar has not hurt. For nineteen years, wizards and Muggles have lived in peace, the latter unaware of the former's existence. Under the hero's watch, justice has prevailed.
But if a hero remains, a villain must rise from the shadows to challenge him.
A Muggle murder catches the attention of the Ministry of Magic when strange messages and chocolate wrappers are found at the scene. Auror Potter is called to investigate, as the message directly involves him.
The hard-won peace that Harry and the world have fought for is about to unravel.

Meanwhile, Albus Severus Potter arrives at Hogwarts School of Witchcraft and Wizardry for the first time. Alongside his cousin, Rose, Albus will soon discover that the school still holds many secrets yet to be revealed.
