The Green Man is Peter's mother's way of dealing with death. Prior to the death of someone close to her, he appears to comfort her. Just before Peter boards a flight, his mother calls to beg him not to get on the plane because she just saw The Green Man. Peter ignores her warning because he doesn't believe in him. But he should have listened because The Green Man is real.
There isn't much to the plot. The story is basically Peter describing the horrors of his flight and how it changed his faith. But it still manages to be exciting and even a bit gory.
The main character, Peter, is just an average guy and I really empathize with him and understand his skepticism about the existence of The Green Man.
My one complaint is that the story is fairly predictable. About halfway through the story I knew how it was going to end. But that didn't make me enjoy the story any less.
"The Green Man" is an interesting short story about faith and how a traumatic experience can change your life. It's available as an e-book from Damnation Books for $2.99.
