Summary
When Harry Potter defeated Voldemort, he hadn't planned to live passed it. A miscalculation that seemed like a gift at first only brought him a crushing empty loneliness since.
He knows there's a piece of himself that's missing and he'll do anything to have it back.
This mentally deteriorating Harry Potter doesn’t dare to claim that he can 'fix Tom' or even that he can 'make Tom worse', only that he will 'have Tom'.
It's not as if anyone would risk themselves to stop him; and if they did, well, none of them could really pose much of a challenge.

Summary
Harry Potter is dead.
Or at least ... that’s what the world believes.
The wizarding world is reeling - the Chosen One, the Boy Who Lived, has perished in something as mundane as a house fire. With his golden pawn gone, Dumbledore scrambles to craft a new savior ... someone who can stand against the rising darkness.But the new Chosen One is not what he seems. Secrets coil around him like snakes, and the cracks in his carefully constructed story are starting to show. Every lie is another card in a teetering tower - and it’s about to collapse.
Worse still, he’s being haunted by a self-absorbed ghost - a former Hogwarts student with a dangerously handsome face, a dangerously bigger ego… and his own agenda.
The world lost its hero.
But what if the lost hero was never meant to save it? -

Summary
After his death, Harry Potter wakes up decades in the past, and takes the position of the new Defense Against the Dark Arts professor at Hogwarts. With his knowledge of the future, he has one goal: stop Tom Riddle before he becomes Voldemort.
But persuasion and reason won’t be enough to change a monster in the making. Perhaps love, carefully brewed and bottled, will do the trick instead.
(Let‘s just hope Harry doesn‘t turn into the monster himself.)

Summary
It is a truth seldom acknowledged, that the brightest of beauties may hide the darkest of hearts.
Harrie Potter was no exception.
“Who the fuck are you?” Harrie lashed out, gripping the crumbling stone behind her, hoping to calm her heart which had started beating like crazy.
“My my for such a pretty girl you have got a foul mouth,” the boy said, because she finally could see his face as he walked closer and came to a stop a few feet from her, which Harrie appreciated. For a moment she wondered whether it was a vampire or if she was dreaming, because surely such beauty didn’t exist in the real world.
“I’m Tom Riddle,” he said, voice deep and smooth with a lilting accent to it that she couldn’t place. “I live in that house over there.”

Summary
No one knows the true battles Hadrian fights not just with the world, but within himself. Beneath his cold exterior lies a fractured mind. He doesn’t just have one face to show the world; he has many.
Hadrian suffers from Dissociative Identity Disorder. Different identities control him at different times each with their own desires, fears, and motives. Sometimes he’s the calculating brother, cold and ruthless. Other times, a lost boy desperate for approval. And sometimes... something darker, something terrifying, surfaces.
This hidden war inside Hadrian is the root of his unpredictable cruelty and his dangerous connection to Voldemort. It’s what makes him more dangerous than anyone suspects.
