A new student at Hogwarts unknowingly becomes part of bet between Draco Malfoy, Lorenzo Berkshire, Blaise Zabini, Mattheo Riddle and Theodore Nott.

Verity Callahan. The Slytherin Princess. The wealthiest girl in all of Hogwarts is also the deadliest. She may look innocent, but to her rebellious friends, they all know it's just a facade. Mattheo Riddle. The Slytherin King. They all know him as the dark lord's son, the infamous death eater, the murderer. The cold hearted boy who doesn't get involved with anyone but the troublemakers of Hogwarts who claim are his friends. Riddles and Callahan's were always allies. So when they partner both of the young death eaters together in a mission to help destroy everything and everyone they love, the two enemies agree to work together to stop their fathers' deadly plan. "I guess it's just you and me against the world, princess." "You wish, Riddle."

A year after the Battle of Hogwarts, Voldemort is dead-but his legacy lives on in his son. Mattheo Riddle, heir of Salazar Slytherin, is ruthless, determined to finish what his father started. By his side: Draco Malfoy, Theodore Nott, Blaise Zabini, Lorenzo Berkshire... and Londyn Remington. Six heirs, trained to fight, conquer, and kill. But Londyn never wanted this life. After witnessing her brother's execution, she became one of Voldemort's deadliest weapons. All she wants now is one last year at Hogwarts, one last chance at freedom. Mattheo has other plans. Loyalty is lethal, hatred turns dangerous, and destiny-written in blood-is impossible to escape.

Evelina Hillgado and Mattheo Riddle come from two of the oldest pureblood families-families that stood side by side during the darkest parts of the war. They grew up around each other. Not friends, not exactly enemies-just two people expected to carry on a legacy neither of them asked for. Now, in their final year at Hogwarts, the pressure is rising. Pureblood families are being pushed to unite through arranged bonds. Rumors swirl. Expectations build. And to keep control of their own lives, Mattheo and Evelina strike a deal: Pretend to be together. Keep their parents satisfied. Stay ahead of everyone else. It's cold. Strategic. Just enough to convince their families the alliance is real. But things shift. People talk. Old childhood memories start surfacing, and the more time they spend faking it, the harder it is to tell what's real-and what's just part of the plan. Their families might be allies. But that doesn't mean they trust each other. And in Slytherin, trust is always a weapon.

When fiery, sharp-tongued Eliana Larkin transfers to the prestigious Hogwarts, shool of Witchcraft and Wizardy everyone assumes it's just another pureblood kid switching schools. But the truth is far more complicated. Sent by her dad with a secret organization to gather the mysterious plans of Voldermort who wants to kill her and her family and to stop him-Eliana's mission is simple: get close, gather intel, and stay under the radar. But she can't get close to his son-Mattheo-because she despises him. Mattheo is arrogant, calculating, and used to getting his way. He instantly sees Eliana as a threat-and she sees him as the arrogant son of a man she's sworn to defeat. Their hatred is mutual, their rivalry explosive, and their every interaction a battle of wills. But as secrets unravel and danger creeps closer, Eliana and Mattheo are forced into a shaky alliance. And when hate starts to blur into something else, they'll both have to ask themselves: how do you trust the enemy when your heart's the one that betrays you first? ---

Estelia Fallon is reckless, rebellious, and completely unimpressed by Mattheo Riddle, the son of the Dark Lord, feared by everyone but her. He thinks she's an infuriating pain in his ass, and she sees him as an arrogant dickhead with an overinflated ego. So when they're forced into an arranged marriage, it's war. Insults fly, tensions rise, and neither of them is willing to back down. But as they navigate a world of enemies, dark secrets, and unexpected alliances, their hatred starts to shift into something far more dangerous. Because the only thing worse than being trapped in a marriage they never wanted... is realizing they might not hate it as much as they thought. #1 in Mattheo 23/9/25

"You're being dramatic." She shot me a sharp look, the kind that would make a lesser man back up a step. "Oh, please. Do you think I don't notice when you're playing mental chess in that oversized head of yours? You dragged us into a meeting with Potter, of all people, and still refuse to tell me why."
