Between the Boundaries comprises twenty-six essays that follow the course of a single year and cover topics that range from the habits of beavers to the progression of Artificial Intelligence, journeying from Wales to Australia with many stops in between. The origins for most have come about by chance; an impromptu stop on a journey has revealed something unexpected and interesting, a poster, a brochure or a website suggesting an event that promised to be out of the ordinary. Politics, technology, art, poetry, and gardening are just some of the subjects on offer here. 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 visits a former nuclear bunker, now made into an unpeopled data centre.
