It's entitled Stranger Than We Can Imagine: Making Sense Of The Twentieth Century and has been written by the twisted genius that is John Higgs.
You may well already know John's work from his hilarious and emotive head-fuck fiction (The Brandy Of The Damned and The First Church On The Moon) and/or his mesmerising non-fiction (The KLF: Chaos, Magic And The Band Who Burned A Million Pounds and I Have America Surrounded: The Life Of Timothy Leary)
I have totally read Stranger Than We Can Imagine: Making Sense Of The Twentieth Century and can tell you it's extraordinary. John has the rare talent of being able to convey a clear-headed overview on complex events and concepts (even quantum physics, for Christ's sake), while weaving a unique narrative and making you laugh, all while utterly shunning the sandpaper-dryness which afflicts so much academic work. This book not only makes sense of the 20th Century: it sheds light on what in the blue blazes is going on right now.
Buy it, I tell you.

I'm only too happy to bask in John's reflected glory, by pointing out that he and I released a joint Kindle book a while back, which bundles his Brandy Of The Damned with my novella Beast In The Basement. Obviously, then, it's called Brandy In The Basement (UK/ US).
