I personally recommend this book quite highly. It focuses on the U.S/Soviet arms race, so slightly out-dated if you want to know about the modern landscape of nuclear arms politics, but many of the same dynamics among the major states (particularly relevant today for Russia and U.S conflict) still apply. It's also an entertainingly written book aside from being very informative.

If you want to relive the terror I suggest reading the Pulitzer Prize winner "The Dead Hand: The Untold Story of the Cold War Arms Race and Its Dangerous Legacy". While its focus is on the Cold War it's still relevant today.

If this article piqued your interest definitely have a look at "The Dead Hand" (http://www.amazon.com/The-Dead-Hand-Untold-Dangerous/dp/0307...).
