NEW YORK TIMES BESTSELLER - "Vital reading for Americans and people anywhere who seek to understand what is happening 'after the fall' of the global system created by the United States" (New York Journal of Books), from the former White House aide, close confidant to President Barack Obama, and author of The World as It Is At a time when democracy in the United States is endangered as never before, Ben Rhodes spent years traveling the world to understand why. He visited dozens of countries, meeting with politicians and activists confronting the same nationalism and authoritarianism that are tearing America apart. Along the way, the Russian opposition leader he spoke with was poisoned, the Hong Kong protesters he came to know saw their movement snuffed out, and America itself reached the precipice of losing democracy before giving itself a fragile second chance. The characters and issues that Rhodes illuminates paint a picture that shows us where we are today--from Barack Obama to a ris

Two identical twin sisters and former child actors have grown apart―until one disappears, and the other is forced to confront the secrets they’ve kept from each other in this twisty suspense novel from the New York Times bestselling author of Pretty Things.“You be me, and I’ll be you,”I whispered.As children, Sam and Elli were two halves of a perfect whole: Gorgeous identical twins whose parents sometimes couldn’t even tell them apart.

After leaving acting, Elli reinvented herself as the perfect homemaker: Married to a real-estate lawyer, in a house two blocks from the beach. Meanwhile, Sam has never recovered from her failed Hollywood career, or from her addiction to the pills and booze that have propped her up for the last fifteen years.Sam hasn’t spoke

"Thrilling . . . a bracing summary of what we have learned [from] 'archaeogenetics'--the study of ancient DNA . . . Krause and Trappe capture the excitement of this young field."--Kyle Harper, The Wall Street JournalJohannes Krause is the director of the Max Planck Institute for Evolutionary Anthropology and a brilliant pioneer in the field of archaeogenetics--archaeology augmented by DNA sequencing technology--which has allowed scientists to reconstruct human history reaching back hundreds of thousands of years before recorded time. In this surprising account, Krause and journalist Thomas Trappe rewrite a fascinating chapter of this history, the peopling of Europe, that takes us from the Neanderthals and Denisovans to the present. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. This Anatolian farmer DNA is one of the core genetic components of people with conte

A bold retelling of the Book of Genesis, starring a female God, from the acclaimed New Yorker cartoonist and author of Passing for Human. In this ambitious and transcendent graphic novel, Liana Finck turns her keen eye to none other than the Old Testament, reimagining the story of Genesis with a God as a woman, Abraham as a resident of New York City, and Rebekah as a robot, among many other delightful twists. In Finck's retelling, the millennia-old stories of Adam and Eve, Abraham and Isaac, and Jacob and Esau haunt the pages like familiar but partially forgotten nursery rhymes--transmuted by time but still deeply resonant. With her trademark insightfulness, wry humor, and supple, moving visual style, Finck accentuates the latent sweetness and timeless wisdom of the original text, infusing it with wit and whimsy while retaining every ounce of its spiritual heft. Let There Be Light is a testament to the fact that old stories can live forever, whether as ancient scripture or as a series

From the congressman who led the first impeachment of Donald J. Trump, the vital inside account of American democracy in its darkest hour, and a warning that the forces of autocracy unleashed by Trump remain as potent as ever. In the years leading up to the election of Donald Trump, Congressman Adam Schiff had already been sounding the alarm over the resurgence of autocracy around the world, and the threat this posed to the United States. But as he led the probe into Donald Trump's Russia and Ukraine-related abuses of presidential power, Schiff came to the terrible conclusion that the principal threat to American democracy now came from within. In Midnight in Washington, Schiff argues that the Trump presidency has so weakened our institutions and compromised the Republican Party that the peril will last for years, requiring unprecedented vigilance against the growing and dangerous appeal of authoritarianism. The congressman chronicles step by step just how our democracy was put at such

The riveting, unforgettable story of a girl whose indomitable spirit is tested by homelessness, poverty, and racism in an unequal America--from Pulitzer Prize-winning journalist Andrea Elliott of The New York Times Invisible Child follows eight dramatic years in the life of Dasani Coates, a child with an imagination as soaring as the skyscrapers near her Brooklyn homeless shelter.

By the time Dasani comes of age, New York City's homeless crisis is exploding as the chasm deepens between rich and poor. In the shadows of this new Gilded Age, Dasani must lead her seven siblings through a thicket of problems: hunger, parental drug addiction,

"Merlin Sheldrake's marvelous tour of these diverse and extraordinary life forms is eye-opening on why humans should consider fungi among the greatest of earth's marvels. . . .

NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Time - New Statesman - London Evening Standard - Science FridayWhen we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree.

Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave. In Entangled Life, the brilliant young biologist Merlin Sheldrake shows us the world from a fungal point of view, providing an exhilarating chan

"This book is a victory on both sides of the page."--Gloria Steinem "Are you one of us?" a patient once asked Marsha Linehan, the world-renowned psychologist who developed Dialectical Behavior Therapy. "Because if you were, it would give all of us so much hope." Over the years, DBT had saved the lives of countless people fighting depression and suicidal thoughts, but Linehan had never revealed that her pioneering work was inspired by her own desperate struggles as a young woman.
