Genesis by Karin Slaughter

Someone had spent time with her - someone well-practised in the art of pain...Three and a half years ago former Grant County medical examiner Sara Linton moved to Atlanta hoping to leave her tragic past behind her. Now working as a doctor in Atlanta's Grady Hospital she is starting to piece her life together. But when a severely wounded young woman is brought in to the emergency room, she finds herself drawn back into a world of violence and terror. The woman has been hit by a car but, naked and brutalised, it's clear that she has been the prey of a twisted mind. When Special Agent Will Trent of the Criminal Investigation Team returns to the scene of the accident, he stumbles on a torture chamber buried deep beneath the earth. And this hidden house of horror reveals a ghastly truth - Sara's patient is just the first victim of a sick, sadistic killer. Wrestling the case away from the local police chief, Will and his partner Faith Mitchell find themselves at the centre of a grisly murder hunt. And Sara, Will and Faith - each with their own wounds and their own secrets - are the only thing that stands between a madman and his next crime.

Meh, I think I might be moving on from Forensic Crime and Mystery ... I can't remember the last *really* good one I read. This one was okay, it had loads of potential, but in the end I felt like Karin Slaughter was just making stuff up out of nowhere to try and get a twist that I didn't really feel held up to the rest of the story-line. Lacking follow-thru would probably be my best description.
