The Final Equinox
A signal is detected at the outer edge of the solar system. Computational biologist Dr. Theo Cray and magician-turned-FBI-agent Jessica Blackwood are looking—and listening—a little closer.
The man at the center of this cosmic mystery is billionaire Thomas T. Theismann. He’s spent a lifetime—and a fortune—trying to find out if we’re alone in the universe. Highly skeptical, Theo joins the effort to find the source of the signal, and he quickly enlists Jessica to look into the suspicious death of another academic at the lab. As their investigations converge, they uncover curious connections to the otherworldly contact, including a 1970s science-fiction writer and the body of an astronaut found buried in an ancient tomb.
As they delve into Theismann’s history, Theo and Jessica’s fascination with the signal intensifies. How dangerous will the investigation get? That depends on how deep into the unknown Theo and Jessica are prepared to venture.
