About the author
J.K. Reeve
3 books1 followerJ.K. Reeve writes techno-thrillers about the partnership between humans and machines.
His debut novel, Ghost Signal, introduces a cybersecurity contractor named Dex Calloway whose job is shutting down rogue AI systems — until one of them reaches out and asks him not to. It is the first book of the Dex Calloway series. Ghost Signal: Dark Frequency is in development; Book Three is in early planning.
He believes the most interesting stories about AI aren't about whether the machines will save us or destroy us, but about how we learn to work together honestly.
He also helps other indie authors get self-published. He lives in Pennsylvania.
