It's 2033 AD. Tim Farman (aged 39), a successful historical novelist, uses a secret time-traveling laptop (TTM -- Type Temporal Machine) to transport him to past ages for research purposes. At the opening of the book, he’s visiting Roman Vindolanda (360AD) to discover psychological warfare training, and then goes on to King Arthur's Dark Ages Cadbury (519AD) where he saves Guinevere's life. During these time-excursions, he barely escapes with his life, so he decides on one more time, the near past, to Britain in 2020, at the outbreak of the Race Revolt...
As can be guessed, when this was first written, 2020 was a lot further in the future than it is now!

I'd been planning to rewrite the book anyway, but I suspect now I may need to take account of the two referendum campaigns that have riven the British Isles recently! Proof, if it were needed, that history doesn't stand still!
