In today's world of cyberspace, there are people who can make the zeros and ones dance to almost any tune. Many of us have experienced a disastrous virus or an email web attack. One has to wonder about a sick mind that tries to inflict damage on innocent people.
Such is the mind of our protagonist as he flits around the Caribbean on cruise ships, killing his victims without pangs of conscience or regret. Only the combined intelligence and the determined effort of several other smart people can even hope to challenge such a person.
One surviving victim becomes the key for a high tech effort by authorities to capture the killer using the very latest electronic technology all the way from Miami's South Beach to Puerto Rico.
You are able to see the cat and mouse antics of people who are masters of their art, experience their pain in the agony of defeat along with the ecstasy of success in an epic battle of minds, all of which precipitates a shocking ending.
