Read again? In a few years
prot returns almost to the minute 5 years after his departure for his homeworld of K-PAX. It's August 17, 1995.
Dr. Brewer had concluded that prot was no alien, but rather an alternate personality created by Robert Porter to defend himself against traumatic situations--first, when his father died, then when he was molested by his "uncle," and most recently--in August of 1985--when his wife and daughter were murdered. When prot left at the end of "K-PAX," Robert became catatonic, curled up on a bed, unresponsive to any stimulus.
Now, prot/Robert has awakened, and prot announces that this time he's leaving for good--and he's willing to take 100 people with him! Brewer only has a few weeks to bring Robert closer to a cure. As he investigates Robert's background and gets more and more of his story from the man himself, Brewer finds that there are more than just Robert and prot living in there:
prot--the alien pal, calm, rational, highly intelligent.
Harry--the protector; he killed the man who killed Robert's family.
Paul--the lover; because of the molestation by his uncle, Robert is seriously messed-up where sex is concerned.
In the meantime, everyone wants to talk to prot--the CIA, biologists, astronomers, and people who want to go to K-PAX. Is he really just an alternate persona? If he is, what happened to the woman who left with him at the end of the last book? Why is there a slight difference in DNA in the blood samples taken from prot and Robert?
As with the first, a light and fun read.
