The scariest book I've read would be The Devouring by Simon Holt. He does a really good job of exposing your childhood fears and forces you to realize no one is as fearless as they think. Very good read and its not too long!

In his recent series Comfort Zone, photographer Tadao Cern explores this contradictory behavior as he captures candid, unsuspecting sunbathers, partially exposed, as they lie asleep on the beach.
