"[A] glorious, glittery saga of friendship and loss... I read The Air You Breathe in two nights. (One might say I inhaled it.)." --NPR "Echoes of Elena Ferrante resound in this sumptuous saga."--O, The Oprah Magazine "Enveloping...Peebles understands the shifting currents of female friendship, and she writes so vividly about samba that you close the book certain its heroine's voices must exist beyond the page." -People The story of an intense female friendship fueled by affection, envy and pride--and each woman's fear that she would be nothing without the other. Some friendships, like romance, have the feeling of fate. Skinny, nine-year-old orphaned Dores is working in the kitchen of a sugar plantation in 1930s Brazil when in walks a girl who changes everything. Graça, the spoiled daughter of a wealthy sugar baron, is clever, well fed, pretty, and thrillingly ill behaved. Born to wildly different worlds, Dores and Graça quickly bond over shared mischief, and then, on a deeper level, over music. One has a voice like a songbird; the other feels melodies in her soul and composes lyrics to match. Music will become their shared passion, the source of their partnership and their rivalry, and for each, the only way out of the life to which each was born. But only one of the two is destined to be a star. Their intimate, volatile bond will determine each of their fortunes--and haunt their memories. Traveling from Brazil's inland sugar plantations to the rowdy streets of Rio de Janeiro's famous Lapa neighborhood, from Los Angeles during the Golden Age of Hollywood back to the irresistible drumbeat of home, The Air You Breathe unfurls a moving portrait of a lifelong friendship--its unparalleled rewards and lasting losses--and considers what we owe to the relationships that shape our lives.

As command module pilot for the Apollo 15 mission to the moon in 1971, Al Worden flew on what is widely regarded as the greatest exploration mission that humans have ever attempted. He spent six days orbiting the moon, including three days completely alone, the most isolated human in existence. During the return from the moon to earth he also conducted the first spacewalk in deep space, becoming the first human ever to see both the entire earth and moon simply by turning his head. The Apollo 15 flight capped an already-impressive career as an astronaut, including important work on the pioneering Apollo 9 and Apollo 12 missions, as well as the perilous flight of Apollo 13. Nine months after his return from the moon, Worden received a phone call telling him he was fired and ordering him out of his office by the end of the week. He refused to leave. What happened in those nine months, from being honored with parades and meetings with world leaders to being unceremoniously fired, has been a source of much speculation for four decades. Worden has never before told the full story around the dramatic events that shook NASA and ended his spaceflight career. Readers will learn them here for the first time, along with the exhilarating account of what it is like to journey to the moon and back. It's an unprecedentedly candid account of what it was like to be an Apollo astronaut, with all its glory but also its pitfalls.

The Guardian's Best Science Book of 2017: 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 Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it. With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation. Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.
