Between the Boundaries follows the course of a single year and covers topics that range from the habits of beavers to the progression of Artificial Intelligence, journeying from Wales to Australia with many stops in between. Humorous, thought-provoking and insightful, it sweeps over and beneath the boundaries, both visible and invisible, that cover the world. The author visits a new assessment of the Elizabethan polymath John Dee, and compares the relative claims to accuracy of different portrayals of Dylan Thomas. He goes underground to a former nuclear bunker, now made into an unpeopled data centre, and he dissects the potential future of the BBC. Pivotal moments in history are revisited, and largely-neglected artists remembered. Between the Boundaries is an eclectic personal journey, fresh and wide in scope, of encounters across genres, eras and continents.
