Publisher's Summary

From the bestselling author of Jurassic Park, Timeline, and Sphere comes a neurological thriller about the dangers of cutting-edge medical experimentation.
Harry Benson suffers from violent seizures. So violent that he often blacks out when they take hold. Shortly after severely beating two men during an episode, the police escort Benson to a Los Angeles hospital for treatment. There, Dr. Roger McPherson, head of the prestigious Neuropsychiatric Research Unit, is convinced he can cure Benson with an experimental procedure that would place electrodes deep in his brain's pleasure centers, effectively short-circuiting Harry's seizures with pulses of bliss. The surgery is successful, but while Benson is in recovery, he discovers how to trigger the pulses himself. To make matters worse his violent impulses have only grown, and he soon escapes the hospital with a deadly agenda....

Ahh.. The Pre-Micro Chip Era

This is a well-written thriller, a cautionary tale of man’s relationship to and with technology. Written in the early 1970s, it was very cutting edge for its time. The fear of technology, especially computers, taking over the world is ribboned throughout the story. I would recommend this listen for its nostalgic (historic?!) value even if you are too young to remember when smoking was allowed in hospital rooms, a female surgeon was an oddity and a file cabinet sized computer was a slick, very expensive science miracle. As thrillers go, it’s not edge of your seat but, as with much of Michael Crichton’s work, it will make you think.

Storey not strong enough

Too many doctors, but without individual enough characters to discern between them. Worth a read, but not at the price.
