Blood Born by Kathryn Fox
A teenager is found barely alive by the roadside, bleeding from her slit throat. The police can't even begin to imagine the horrors she has faced. For inside their house lies the girl's older sister: brutally tortured, raped and stabbed to death.
As the girl struggles for survival, forensic scientist Anya Crichton is brought in to examine the evidence, all of which points towards a well-known family of career criminals.
However, it soon becomes clear that they will stop at nothing to evade the law.
Even if others have to die.
