Like him, I'm a sceptic. But he does a better job, than any book that I've ever read, on bringing "structure" and clarity of thought to what happens next. To the extent there's science around what happens to us when we die, Martini tries to capture it. At a minimum, he's able to communicate common threads that'll force even the most jaded among us to ponder - what if.
My advice - READ THIS BOOK!
