Primordia - kindle ebook by T. A. Bradley

The idea for this horror story came from personal experience. Before
becoming a full-time writer, I worked as a virologist for several
biotech companies, the last of which had biodefense contracts with the
government. Needless to say, I've worked with some pretty nasty
viruses. This story came out of a "what if" scenario that came to me
while I was lying in a hospital bed, two days after I'd had a pacemaker
It started when I thought about what would happen down the line when the
battery had to be replaced...and from there I developed the idea for an
implantable device that would not need surgery to be recharged. The
rest was a journey of pure imagination that wound me through the darker
corners of my mind.
