Plot: Ryan Perry is 34 years old, wealthy and in love. His life is wonderful until he discovers he has heart disease and needs a transplant. His life spins out of control as he becomes suspicious of everyone around him and doesn't know what is real, what is paranoia, and what is a side effect of the regimen of drugs he must take. He undergoes a successful transplant, but strange occurrences continue.
I'm a big fan of Dean Koontz, but this is not one of his best. The characters are not as engaging and endearing as Koontz' characters usually are, and the plot is full of holes.
