Writers are eavesdroppers by nature. We are also voyueristic.
A few decades ago we had to have a great memory or a scratch pad to capture the moment we just saw.
This writer took a huge chance on me, the reader, by taking me far far outside my experience. Mark Jude Poirier made me participate in in the story as a gay teacher and for the length of the story I felt his lust for a student at his school. I will think about his motivation and the repercussions of his actions. More than that, I will think about what it was like to be this character.
