The Double Down series continues with two men, and some interesting issues they contend with—two stories, two authors, one book. There was a time when Pete felt like he had the world in the palm of his hands, but lately everything is falling apart. His wife is growing cold, his business is in trouble, and even his friends show him nothing but contempt. Then a neighbor introduces him to paleo—the old way of eating, exercising, and even communing with the ancient sprits of the Neanderthals. All it takes is a little work, a little discipline, and a little blood sacrifice, and mysterious powers are within his grasp, but there's a price Pete never expected. It's a dark tale of terror, revenge, and suburban fads.

Eric can sell insurance, but he can't sell anyone on what he knows for a fact: this world is about to go down in flames. Eric is forced to prep in secret. His wife won't listen, neither will his clients. But Eric's worst enemy has been making careful plans, and now he's ready jump start the destruction. It's the end of the world as we know it, and all the worst people are the best prepared.
