Imagine a blackout lasting not days, but weeks or months. Tens of millions of people over several states are affected. For those without access to a generator, there is no running water, no sewage, no refrigeration or light. Food and medical supplies are dwindling. Devices we rely on have gone dark. Banks no longer function, looting is widespread, and law and order are being tested as never before.

After Hurricane Katrina struck and power failed, amid rising floodwaters and heat, exhausted staff at Memorial Medical Center designated certain patients last for rescue. Months later, a doctor and two nurses were arrested and accused of injecting some of those patients with life-ending drugs.

On April 15, 2013, two homemade bombs exploded near the finish line of the Boston marathon, killing three people and wounding more than 264 others. In the ensuing manhunt, Tamerlan Tsarnaev died, and his younger brother, Dzhokhar, was captured and ultimately charged on 30 federal counts. Yet long after the bombings and the terror they sowed, after all the testimony and debate, what we still haven't learned is why. Why did the American dream go so wrong for two immigrants?

With temperatures rising and the risk of disasters growing, our world is increasingly vulnerable. Most people see disasters as freak, natural events that are unpredictable and unpreventable. But that simply isn’t the case - disasters are avoidable, but when they do strike, there are strategic ways to manage the fallout.

The retired four-star general and and best-selling author of My Share of the Task shares a powerful new leadership model. Former General Stanley McChrystal held a key position for much of the War on Terror, as head of the Joint Special Operations Command. In Iraq, he found that despite the vastly superior resources, manpower, and training of the US Military, Al Qaeda had an advantage because of its structure as a loose network of small, independent cells. To defeat such an agile enemy, JSOC had to change its focus from efficiency to adaptability.

In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance to simultaneously reduce gaping inequalities, re-imagine our broken democracies, and rebuild our gutted local economies.

Start-Up Nation addresses the trillion dollar question: How is it that Israel - a country of 7.1 million, only 60 years old, surrounded by enemies, in a constant state of war since its founding, with no natural resources - produces more start-up companies than large, peaceful, and stable nations like Japan, China, India, Korea, Canada, and the UK?

A fresh window on American history: the eye-opening truth about the government's secret plans to survive a catastrophic attack on US soil, even if the rest of us die - a road map that spans from the dawn of the nuclear age to today.

In 2014's The Accidental Superpower, geopolitical strategist Peter Zeihan made the case that geographic, demographic, and energy trends were unravelling the global system. Zeihan takes the story a step further in The Absent Superpower, mapping out the threats and opportunities as the world descends into disorder.

The Border Patrol has grown exponentially, ICE detention centers have cropped up across the country, and the southern border is more militarized than ever before, but we are no safer. Instead, families are being ripped apart, undocumented people are living in fear, and thousands of migrants have died in detention or crossing the border. Taking listeners to the border patrol outposts, unmarked graves, detention centers, and halls of power, Sand and Blood is a frightening, essential story we ignore at our peril.

The world is changing fast. Political risk - the probability that a political action could significantly impact a company's business - is affecting more businesses in more ways than ever before. A generation ago, political risk mostly involved a handful of industries dealing with governments in a few frontier markets. Today, political risk stems from a widening array of actors, including Twitter users, local officials, activists, terrorists, hackers, and more. In today's globalized world, there are no "safe" bets.

American military bases encircle the globe with nearly 1,000 locations in foreign lands. These bases are usually taken for granted or overlooked entirely. But, in an eye-opening account, Base Nation shows that the worldwide network of bases brings with it a panoply of ills - and actually makes the nation less safe in the long run.

Warnings is the story of the future of national security, threatening technologies, the US economy, and possibly the fate of civilization. In Greek mythology Cassandra foresaw calamities, but was cursed by the gods to be ignored. Modern-day Cassandras clearly predicted the disasters of Katrina, Fukushima, the Great Recession, the rise of ISIS, and many more. Like the mythological Cassandra, they were ignored. There are others right now warning of impending disasters, but how do we know which warnings are likely to be right?

One of the threats facing our nation is the use of an EMP weapon to cause a grid down scenario. There are many bad actors on the international stage capable of terrorism on a massive scale. The list is long, including Russia, China, North Korea, Iran, Syria and now terrorist groups like ISIS. Each is capable of wreaking havoc in the US by shutting down our power grid through the use of an EMP, and enjoying the resulting chaos.

In Your Government Failed You, Clarke looks at why failures have continued and how America and the world can succeed against the terrorists. But Clarke goes beyond terrorism to examine the recurring U.S. government disasters. Despite the lessons of Vietnam, we've gotten involved in Iraq. Drawing on his 30 years in the White House, Pentagon, State Department, and Intelligence Community, Clarke discovers patterns in the failure and suggests ways to stop the cycle.
