OC x Carlisle Cullen / Caius When Bella Swan disappears after her wedding, her family is left with half-truths and unanswered calls. Weeks turn into months, and all Clara hears is that her sister is "sick" and "needs time." But Bella's distant words don't sound like her anymore - and the silence that follows feels like betrayal. As Bella's strange new life unfolds far away, Clara struggles to hold her family together - especially their father, who still believes his eldest daughter will come home. But when Bella finally reappears, changed in ways Clara can't explain, old wounds reopen. The sister she loved is both familiar and utterly foreign. Drawn into the orbit of the Cullens, Clara finds herself unexpectedly confiding in Dr. Carlisle Cullen - the man who once seemed only her sister's friend. His calm understanding becomes her anchor in a world that makes less and less sense. Yet the more she learns, the more she senses the truth he cannot tell her... and the quiet ache between them neither can admit. In a place where truth is deadly and love is no longer human, Clara must decide how much of her heart she's willing to risk for someone who stopped being mortal long ago.

She was never meant to burn. But when Carlisle Cullen made the impossible choice to turn a dying girl, he didn't realize he was igniting something the world had never seen. Vivienne St. Claire was meant to die in 1974 - fragile, fevered, too human for a world at war. Instead, she woke in flames. A vampire unlike any other. Eyes still blue. Blood still bound to the sun. And a heart that never forgave the man who gave her eternity. She vanished. Decades passed. She tried to forget the Cullens. But the Cullens never forgot her. Until a new war rises, this time not from bombs, but from the volturi. And the only weapon strong enough to stop them is the girl Carlisle once called his daughter. Now Vivienne is back. With fire in her hands. Light in her veins. And a family she never asked for waiting in the ashes. What burns brighter - vengeance or the blood you share?

All Alexandra wanted to do was escape from her father. To do that, she follows her older brother to Dauntless where she is submerged into a whole new way of life. She embraces the Dauntless lifestyle with open arms, but becomes the target of Dauntless' youngest leader. As her brother pulls her in one direction to hide her Divergence, she pulls back, and ends up closer to the cruel young leader than her friends and brother would like. (Eric/OC)
