This is Carl's Brain
The Rainbow Virus by Dennis Meredith

In The Rainbow Virus, the FBI and CDC are chasing a bizarre virus unleashed by Arthur Lupo, a strange little scientist.  Instead of unleashing chaos and killing millions, the virus changes the color of the infected person.  The colors are varied, across all spectrums of the rainbow (hence the name).  The two primary people on the chase are FBI agent, Bobby Loudon, and CDC scientist, Kathleen Shinohara.  It was clear from the beginning that these two would eventually become a couple, something that was too obvious and telegraphed from the beginning of the story.  Their belief is that the change in colors is only the beginning, and that Arthur Lupo has mass extinction as his intent.

 

The writing in the novel was pretty strong.  It was professional and competent, and I don’t have much to quibble about it.  I really liked the whole concept of the Rainbow virus.  Typically in novels of bioterrorism, the antagonist is sinister from the jump, but in this novel, the initial viruses were more light-hearted in nature.  After all, nobody was truly getting hurt unless they were particularly offended by their shade of color.  Although I generally like the characterization in this novel, I didn’t find Arthur Lupo to be a particularly credible character.  His motivation for doing all he did was thin.  It was explained that his parents died at an early age.  Well, many people have their parents die but they don’t attempt to infect the world with virus.  I also didn’t like “the faction”, which was a stereotypical nameless, faceless government organization with unbound ruthlessness consisting of high ranking members of government and law enforcement with nefarious intent.  The good guys were better developed and more resembled real people with real motivations.

 

There was good tension and this novel was overall a fun read that I would recommend.
