O'conner twins

Brian O'conner has a twin sister. But they ended on bad terms when he decided to be a cop. He can't help but to think that she was right when she said that he belonged to the streets and he was trying to fool himself into being a cop. Especially after all he's been through with Dom and the family. Now years later (after Letty dies) he tries to find his sister again with the help of the family. But finds it unnecessary when she shows up on the front door step of the family's home. But she's got a secret she's hiding from her own brother. What will he do once he find out what has caused his headstrong smart mouthed sister to become so scared of her own dreams? How will the family deal with another O'conner in their mists?
