Whilst I generally enjoy Jance's books, the Ali Reynolds series are not my favourite, but this was a good one, though I've already read many of the ones later in the series.

A man is dragged to his death by a car; Ali is suffering the loss of her marriage and career; a friend's teenage daughter has disappeared. How are they all connected?

With a 12 year old myself, this was at times distressing to read, but was a good reminder to keep an eye on your kids' internet/chat habits
