A fine brief history of Winston Churchill's political carrier. I feel like the author could stand to include more context to the events around which Churchill was maneuvering, rather than sticking so rigorously to the politics. It also seems to me that Addison views Churchill through rose-tinted glasses (the title is already good evidence for that). Churchill is a controversial historical figure, and Addison kinda brushes over his controversies.
I am severely disappointed by this book. I loved the previous oxford time travel books, and this one seems to have much lower quality. Rather than the focus on one or two characters, this book juggles 6 characters at 6 different events, not giving nearly enough time to any of them. It still has one of the best time travel mechanics in fiction, so I'll probably keep reading just to see where we go with that, and Willis is still a competent writer, but she used to be excellent.
EDIT: Having read All Clear, I'm willing to give this book more credit, as it's massive amount of characters actually had some meaning rather than just cluttering the narrative.
