Fractured by Teri Terry

The second book in the Slated trilogy opens with Kyla shivering in the aftermath of the trauma of having attacked a man.  She was only defending herself, however, she has beaten him nearly to death and as a Slated it should not be possible.  Slated's are under 16s that have had their minds and personalities wiped, and they wear a device called a Levo that monitors their mood and if they show signs of agression render them unconsious, even kills them.  It began as a utopian idea, in the aftermath of civil unrest Slating was an alternative to execution.  But Kyla's memories are beginning to return, another things that is not supposed to happen.  There is a man with pale blue eyes at her school, he is supposed to be a teacher but isn't.  Kyla grieves for Ben, the boy she lost in Slated when he cut his Levo off and was last seen being dragged off by the Lorders, the martial police of this new world. Kyla begins to remember and her memories are fractured, of a girl called Rain, of a girl called Lucy, and what exactly was done to her.  She finds herself torn between the new family she has been assigned, her past and her sense of right and wrong. 

An enjoyable read, just don't expect too much from it.  Many of the themes aren't new, a dystopian world with lots of twists and turns, but it is a good ride.
