I'm with lLeMarchand on this -
the notion that a major retailer would devote an entire section to this type of book is disturbing.
It does evidence the current trend towards 'grief-lite' - the notion of 'suffering' on behalf of complete strangers, as depicted by the current media obsession with the Madeline McCann story.
I would not for one minute wish to minimise or defer in ay way the tragedy of this instance, but the constant reference to it when in reality, nothing of significance has happened shows more the need for readers to remotely wring their hands and cast more judgement in the direction of the poor parents, than any possibly helpful approach, or soloution.
Likewise, these books probably do far more for bank balances than for emotional stability on the part of the writers.
The last serious emotional trauma I suffered I did eradicate the worst of the pain by writing it all down, but i dnd't try to get it published - i merely posted it to my closest friend, who has kept it safe, and never mentioned it again, and would not, unless I did.
The catharsism worked - I am just missing this six-figure bank balance to go with it.
