PLAYGROUND by Richard Powers

About emotional responses while reading. Time is controlled in a way reality rarely allows. The feelings can fall and rise, fly and sink, as in a warp. Fear, anger, sadness and joy can occupy the same moment and the experience mined for varied nuance, combinations savored and explored. Or, the onrush of insight afforded by the elevated point of view of observer can allow the tears to well, willingly or resentfully, toward release. How we release is our secret measuring tool of the reaped rewards of reading.
