When a bad boy meets a bad girl does it make them worse?

Ian and Mickey adopt a 16 year old girl who had been beaten and abused by her parents. Will they be able to help her? Or will she be broken forever. This is an x reader story (the character was originally name so chapters will have the name Rachel please ignore this I am trying to edit)

Ian and Mickeys life after they get married. A few surprises come their way. Having to face and overcome old traumas and new. Doing and saying things they never thought they'd say. But as long as they have each other they know everything would be ok.
