Jasper and Demetri turned up one night outside Bella's house to let her join the Volturi. Edward left her, right? So what's the use of all the crying and sulking around under Charlie's roof? But would she still mope around after knowing that her true mate wasn't really Edward? But Jasper?

Ok, long story short, Bella is actually Carlisle’s little sister. They both “go missing” on the same night. They are actually changed into vampires, completely oblivious about the other. They both hide away and discover the vegetarian option for vampires. Cullens stay the same and have no idea about Bella’s coven until they meet up in Forks. How will Carlisle react when he finds out that his little sister is alive? How will Esme react when she finds out that the same goes for her little sister? How will the kids react to the new coven? And, to add even more confusion and chaos to all of it, Edward falls for Bella.
