Fiction
Black Circuit: Thread 72
by J.S. Grant
It's an international thriller that starts with a woman waking on a long-haul flight where everyone around her is unconscious. Black Circuit, a hidden dark-web betting platform, is running her long-haul flight as its current thread, Thread 72, and unseen people have money riding on it. As the mystery widens, so does the human field, across generations, cultures, and continents, with people proving more capable, more vulnerable, and more connected than they first appear.
Release: January 12, 2027, on Kindle, with the paperback out a little earlier.
Paperback ISBN 978-3-9524667-9-7. Ebook ISBN 978-3-9524667-2-8.
