Renesmee has a twin sister who is an outcast in the family. Before the Volturi come, Alistair finds her hiding in the loft and takes her downstairs to Eleazer and the others. Eleazer finds out she's a conjurer but can keep the other’s powers for an unlimited time. She is reluctant for her family to know because she is already different from the rest (she can only live off human blood). They find out and become uneasy around her, not wanting their own gifts to be copied. Alistair befriends her and so do Vladimir and Stefan, and Peter and Charlotte.
They realise the Volturi will want her so might attack in order to add her to Aro’s Collection and decide it would be best if she leaves, and Alistair takes her away as he would have the best chance of avoiding Demetri. Peter and Charlotte refuse to leave her so go with them. Vladimir and Stephan also struggle with being parted from her. Months after the fight with the Volturi Jasper and Alice visit Peter and Charlotte only to find Alistair and Reece with them as well. The Cullens had forgotten about her and Peter and Charlotte had raised her as their own with Alistair dropping by frequently. But what will happen when they receive a visitor from the past?
