In reply to franksnb:
Obviously none of us can speak for him but I strongly suspect Andy Kirkpatrick wouldn't be offended by what JLS was saying because, from what I can tell based on the pre-release blurb I've read, his newest book is largely about questioning whether what he does is actually worth the cost to him and those he loves.
"Psychovertical was a book about a man who is struggling: against the wall, against himself, but who wins through. The story is a hundred thousand word answer to the question: 'Why do you climb?' Cold Wars asks a different question: 'What is the price?'
He has more success, but the savagery and danger of these encounters comes at huge personal cost. Questioning his commitment to his chosen craft, he is torn between family life and the dangerous path he has chosen."
