K-PAX III: The Worlds of Prot by Gene Brewer completes the trilogy of prot–an alter identity of Robert Porter–who has relapsed after his remarkable recovery in On a Beam of Light. Unfortunately, K-PAX III seems to have been written only to fill out the trilogy. In fact, there’s very little story to be found.
As readers of the first two novels, we already know the fairly complex story of how prot came to be, and about Robert Porter’s tragic life. What’s not known completely, is whether prot is truly another life form, inhabiting Robert’s body, or–as Dr. Gene Brewer believes–another personality within Robert’s fragmented mind. In K-PAX III, the answer is revealed vaguely, but brings the series to a fairly satisfactory close. Readers will learn the truth about Robert, and the mystery of his traumatic upbringing, through the sometimes redundant work of Dr. Brewer.
