'I don't know how much longer I'll be here. Maybe I'll have another five years. Maybe, with the advances in oncology, they'll find new treatments for my cancer that will extend my life. Maybe I'll be gone before you read this. My predicament is, well, rather unpredictable. But I'm prepared for either contingency, or at least I'm getting prepared. I have some things I'd like to take care of first, some work that needs finishing, and some people I need to see. And I want to talk to my fellow Americans a little more if I may.' Written while confronting a mortal illness, John McCain looks back with appreciation on his years in the Senate, his historic 2008 campaign for the presidency against Barack Obama, and his crusades on behalf of democracy and human rights in Eastern Europe and the Middle East. Always the fighter, McCain attacks the 'spurious nationalism' and political polarization afflicting American policy. He makes an impassioned case for democratic internationalism and bi-partisanship. He tells stories of his most satisfying moments of public service, including his work with another giant of the Senate, Edward M. Kennedy. Senator McCain recalls his disagreements with several presidents and minces no words in his objections to some of President Trump's statements and policies. At the same time, he offers a positive vision of America that looks beyond the Trump presidency.

The former Republican presidential nominee chronicles his political career from the election of Barack Obama through the divisive 2016 election, offering his opinions of the current developments in Washington as well as his recommendations for ongoing international challenges.
