It’s difficult to come up with a better explanation for what this book is like than the description on the back: Depraved New World (affiliate link) is a worryingly funny collection, which captures British politics at its most absurd. 
It’s a collection of John Crace’s political sketches, originally published in the Guardian, covering October 2021 to June 2023. A pretty eventful time in British politics.
Reading it now, in late 2023, is probably the perfect time. Much earlier and you can’t tell the “good” sketches or consequential events from the average ones. Much later and you’ll have forgotten some of the important details that are being written about. They’re sketches, not analysis of the events or a history. Between the chapters are occasional colour about what was going on, but, broadly, you’re on your own. Political geeks only! Some parts I’d forgotten, but smiled when I recalled. If you’d come across Braverman stepping on a guide dog’s tail on The Thick of It, you’d dismiss it as too unlikely and contrived.
If there’s a trend for the books I’ve read this year, it’s “entertaining but not a classic.” I would put “Depraved New World” in the same category.
