Fractured - Karin Slaughter

Fractured is the first book I've read by Slaughter.  Abigail Campano came home to her fancy estate to find her daughter lying dead in the upstairs hallway.  She's then attacked by the killer and manages to strangle him to death.  Is that really what happened?  It seems that way at first but nothing in this thriller is what it seems.  The mystery begins to unravel when an unlikely pair of law enforcement officers are teamed up to work the case.  One of the detectives has manage to hide the fact that they can't read or write, and strangely this may give the team the big break they need.  Will the break come in time though?  This is one I had a hard time putting down.  Very highly recommended.
