Of Blood and Eternity (K.M.)
She was the first immortal.
A witch born before time itself, cursed with siren's blood, bound to eternity, and destined to be forgotten.
Once, at Hogwarts, she was known as Seraphina Thorne, the brilliant Slytherin who captured Tom Riddle's attention and unknowingly helped him become what he was meant to be. When she discovered the truth, she couldn't kill him, so she cursed him to sleep, never knowing her mercy would one day awaken as Voldemort.
Now, centuries later, she's been summoned back to Hogwarts by Dumbledore himself to teach a new subject: Mythical Creatures and Unknown to This Day.
No one knows she's the same girl whose portrait still hangs in the Slytherin common room.
No one but Kol Mikaelson, the immortal who's loved her across lifetimes, and the one she never dared to love back.
But when old magic begins to stir beneath the castle walls, Seraphina must face the monster she created, the man she lost, and the truth about what it really means to be eternal.
