I wrote Agent Sellar as an exercise.. but decided to sell it as a Kindle e-book and paperback novel... It has been around for a while but I managed to get Chat GPT 4o to review it after uploading it and explaining my "angle". This is what GPT 4o had to say:- "Agent Sellar is a subtle blend of espionage, surrealism, and dry wit. John Sellar’s quest for a mysterious box is both thrilling and absurd. Clever and enigmatic, it rewards readers who enjoy hidden depths." I hope readers will enjoy the novel in the future...
