Darius Amari was a research scientist dedicated to helping humanity conquer deadly viruses. His laboratory studied the superior immune systems of bats. But then, the COVID-19 virus came along and caused Darius to suffer permanent heart damage after barely surviving the pandemic.
Darius was hovering on death's doorstep when his life was saved by an organ donation made by the family of a young accident victim. After the successful transplant however, there were unexpected changes in this brilliant scientist. He developed new interests, behaviors, and vulnerabilities that were not compatible with working with highly lethal germs. As his associates worried that he could unleash a bioterrorism disaster, the associates of the donor struggled with the secret that the heart had previously belonged to someone who was filled with rage.
Was it Darius's new heart that turned him into a different person, or was there a hidden someone inside this scientist that emerged after he lost his battle with a virus? Had the virus changed his brain? Could a transplanted heart retain the donor's state of mind? Darius's young wife, Doctor Thea Baccay, searches for answers to these questions.
