This science is not fiction... mostly.
A real-life parasite already infects over half of all mammals, including humans. Once inside, this parasite reprograms the brains of its hosts.
A series of volcanic eruptions set off those who are infected and whose body temperatures rise above 99 degrees, causing them to go mad with rage and a need to kill. These “Parasitics” have red irises, acute auditory, and visual abilities. They’re stronger, completely fearless, and they can heal quicker than the uninflected population.
Some of those who are infected are only "Symptomatic." They still possess many of the same enhanced abilities of the Parasitics, but are able to remain in control of their violent desires. However, they’ll need to keep their bodily temperatures below 99 degrees or they, too, will become Parasitic like the others and lose all control.
Welcome to the world of MADNESS. The initial trilogy sets the stage for the world and takes place over a period of two weeks onboard the cruise ship Intrepid. The ship leaves Europe just as the chaos begins, with our main characters, a middle-aged couple (Ted and TJ), finding themselves as front row witnesses to the outbreak. Using their unique skills, they help their ship fight to survive in their changed world overrun by madness.
A very small part of the story has been told onboard a cruise ship. But so much more needs to be written by you in the MADNESS WORLD™. Here are a few possible story ideas:
There’s a specific science to the Rage disease that is outlined and explored in the initial MADNESS trilogy. Be sure to read these books. You’re welcome to write anywhere else in the world you'd like, provided the codex of the MADNESS Chronicles is followed. The readers will expect you to follow the rules of the infected world, as outlined in the initial trilogy. The only exception as to location would be onboard the Intrepid where most of the initial trilogy takes place. You can't use that location.
