And here is the bleak new world of the day after: a world stripped of its institutions and emptied of 99 percent of its people. A world in which a handful of panicky survivors choose sides - or are chosen.

Ellen Boehm, a single mom from St. Louis, Missouri, appeared devoted to her children. But in reality, she was unequipped for motherhood, financially strapped, and desperate. Within a year of each other, her sons, ages two and four, died mysteriously, and Boehm's eight-year-old daughter then suffered a near-fatal mishap when a hair dryer fell into the girl's bath. While neighbors wondered how Boehm remained so calm through it all, Det. Sgt. Joseph Burgoon of St. Louis Homicide had darker suspicions.

In April 1944, Rudolf Vrba became one of the very first Jews to escape from Auschwitz and make his way to freedom—among only a tiny handful who ever pulled off that near-impossible feat. He did it to reveal the truth of the death camp to the world—and to warn the last Jews of Europe what fate awaited them. Against all odds, Vrba and his fellow escapee, Fred Wetzler, climbed mountains, crossed rivers, and narrowly missed German bullets until they had smuggled out the first full account of Auschwitz the world had ever seen.

For the last 16 years, Sue Klebold, Dylan's mother, has lived with the indescribable grief and shame of that day.
