A "massive work of dizzying originality" (Boston Globe), XX is an inventive and boldly designed science-fiction epic by acclaimed graphic designer Rian Hughes—now in paperback The battle for your mind has already begun. At Jodrell Bank Observatory in England, a radio telescope has detected a mysterious signal of extraterrestrial origin—a message that may be the first communication from an interstellar civilization. Has Humanity made first contact? Is the signal itself a form of alien life? Could it be a threat? If so, how will the people of Earth respond? Jack Fenwick, artificial intelligence expert, believes that he and his associates at tech start-up Intelligencia can interpret the message and find a way to step into the realm the signal encodes. What they find is a complex alien network beyond anything mankind has imagined. Drawing on Dada, punk, and the modernist movements of the 20th century, XX is assembled from redacted NASA reports, artwork, magazine articles, secret transcripts, and a novel within a novel. Deconstructing layout and language in order to explore how ideas propagate, acclaimed designer and artist Rian Hughes's debut novel presents a compelling vision of humanity's unique place in the universe, and a realistic depiction of what might happen in the wake of the biggest scientific discovery in human history. Propulsive and boldly designed, XX is a gripping, wildly imaginative, utterly original work.

Approached by the Intelligence Force to help in the release of VIPs held by the Germans in is last year at school and the last year of World War II, Glyndwr afterwards returns to real life, looking for a job he likes and can do. Years later he is drawn back to help the Force and they offer an expected incentive. This becomes a pattern for his life. This story, written in the late 1970s, remained undiscovered until three years after the authors death in 2014. Much of it was familiar but the sections involving Operation XX were completely unknown. At first it was thought the title referred to the group of boys trained for the first operation but internet searches brought to light the double meaning of XX: 20 (in Roman numerals) and double-cross. Operation XX was set up in 1941 to use captured German spies to feed back misinformation to Germany. It eventually came under MI5. Glyndwr always questioned what choice, if any, he had in the events and the way life took him. For his family the discovery of the story raised many questions that may never be answered.
