First from this NZ based, Swedish born author.
From the Blurb:
Karen's life is abruptly thrown into chaos when her flatmate is gunned down in front of her in the street where they live.
Within days she is forced to take drastic action to ensure her own safety. She criss-crosses New Zealand to evade the killers, changes her appearance and settles into a small community as 'Cara'. But danger still stalks her and she is forced to make dramatic choices in the face of threats and brutal violence.
