Perfect Match by Jodi Picoult
Nina Frost's occupation as an Assistant District Attorney specialising in child abuse means she spends her days in court trying to protect her young victims and winning for them the satisfaction of their violators being sentenced. Thus she protects herself from getting too personally involved. However, when Nathaniel, her five year old son, drops the bombshell that he has been abused, Nina is sent reeling into the world of extreme protectiveness that only mothers can feel for their own children.
How far will Nina go to avenge this intrusion on her child's life?

I thought this book might have been a bit of a tricky subject but the reader gets so involved and can physically feel Nathaniel's own sorrow, plus his bewilderment at what is happening to his parents. This was the first book by this author that I have read but will delve into her others now.
