Black (J. Cameron) (HP/Twilight crossover) by youngblood2354

Lyra Black is the daughter of Sirius Black. She's been through a lot throughout her seventeen years of life. As soon as she turned seventeen, she ran away from her old life and went straight to the States.

The Dark Lord is rising in ranks, meaning more and more people are dying or becoming Death Eaters. Being a pure blood Slytherin meant Lyra was one of the main people chosen to be a Death Eater. Lyra refused to be on the dark side, but at the same time, she refused to work under Dumbledore. Dumbledore was a joke, and she seen straight through his lies. When Lyra went to the States, she kept in contact with her uncle, Remus Lupin, and his wife, Nymphadora Tonks. Lyra loved Lupin and Tonks more than anything, so it hurt for her to leave them behind, but she had to get away to stay alive and protect everyone she loved. She had lost almost everyone, and she refused to be the reason she lost anyone else. Moving to Forks, Washington was a huge change. She didn't know what to expect when she moved there, but she really didn't expect to find shapeshifters and vampires close to where she lived. She was different as well, but she believed she was alone. She didn't expect to find someone to love, nor did she expect for things to fall apart around her more than they already had. Read to find out more about Lyra's story...

ONCE UPON A BROKEN STAR (TVD/HP/ORIGINALS) by AnjaniManda8

After the war, Lyra Potter is utterly, completely, and unapologetically done with the wizarding world. The media? Shitstorm. The Ministry? Corrupt as ever. The so-called Light Lords? Idiots. The so-called Dark Lords? Even bigger idiots. So, despite her well-meaning (but infuriating) friends, Lyra packs up, flips the wizarding world the metaphorical bird, takes her godson Teddy, and vanishes. Her destination? Mystic Falls. A quiet, unassuming town where one of her Black ancestors once built a lavish estate-the Black Palace. She hopes for peace and quiet-a fresh start, away from magic, war, and endless expectations. But deep down? She knows better. There is no peace for her. Why? Because she is, after all, Death's Little Angel of Chaos. And a Potter. She doesn't seek trouble. Trouble finds her. And so, before she even realizes it, she's swept up in yet another whirlwind- Only this time, it's not scheming politicians, megalomaniac wizards, or dark prophecies. This time, it's- Vampires. Werewolves. Shapeshifters. Doppelgängers-apparently, she's one. An ancient ancestor who oddly approves of her. An annoying twin she has zero interest in. Two ridiculously dramatic vampire brothers. And an entire family of goddamn Originals. What has the world come to? Nothing. Just a storm called love hitting her in the most unexpected way. Her? Entangled with the Original Hybrid of all people? And did she mention she has her little godson with her? "You have got to be joking," she thinks.
