Science is a force for good in the world—at least usually. But sometimes, when obsession gets the better of scientists, they twist a noble pursuit into something sinister. Under this spell, knowledge isn’t everything, it’s the only thing—no matter the cost. Bestselling author Sam Kean tells the true story of what happens when unfettered ambition pushes otherwise rational men and women to cross the line in the name of science, trampling ethical boundaries and often committing crimes in the process.

Early studies of the human brain used a simple method: Wait for misfortune to strike - strokes, seizures, infectious diseases, horrendous accidents - and see how victims coped. In many cases their survival was miraculous, if puzzling. Observers were amazed by the transformations that took place when different parts of the brain were destroyed, altering victims' personalities. With the lucid, masterful explanations and razor-sharp wit his fans have come to expect, Kean explores the brain's secret passageways.

The fascinating science and history of the air we breathe. It's invisible. It's ever present. Without it, you would die in minutes. And it has an epic story to tell.

In April of 1846, 21-year-old Sarah Graves, intent on a better future, set out west from Illinois with her new husband, her parents, and eight siblings. Seven months later, after joining a party of pioneers led by George Donner, they reached the Sierra Nevada Mountains as the first heavy snows of the season closed the pass ahead of them. In early December, starving and desperate, Sarah and 14 others set out for California on snowshoes and over the next 32 days endured almost unfathomable hardships and horrors.

From New York Times best-selling author Sam Kean come more incredible stories of science, history, language, and music, as told by our own DNA. There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking.
