Written by Sten Rynning, NATO: From Cold War to Ukraine... is a comprehensive book about NATO, covering from its very origins to the latest developments.
It's mostly an interesting book, especially in how it demystifies the aura surrounding NATO, showing all its complexities and flaws as well as past, current and future challenges. The book, of course, also covers NATO's (few) successes.
Although the subject is interesting and the information is worth reading, the writing style of S. Rynning isn't particularly engaging. Actually, at times, it is rather boring.
In summary, if you are interested in NATO's history, present and future, I recommend reading this book. Do not expect a non-stop reading experience, though.
