Memórias da Era Dourada: Relatos de Vida nas Melhores Décadas da Humanidade é uma jornada nostálgica pela vida de Lucas, um brasileiro nascido em 1955, que revive as décadas de 1950 a 1970 como o auge da humanidade. Atraves de suas memorias, o livro celebra a fartura da Revoluço Verde, que trouxe abundancia as mesas, a revoluço tecnologica dos transistores aos primeiros chips, o brilho do futebol com Pele e Cruyff, a musica unificadora dos Beatles e da bossa nova, e o hiato de paz que permitiu avanços nos direitos civis e na contracultura. Agora idoso, em 2025, Lucas reflete sobre esses anos vibrantes, contrastando-os com as crises modernas, e deixa uma carta aos netos, inspirando-os a recriar um legado de prosperidade e harmonia. Com uma narrativa envolvente, o livro e um convite a redescobrir uma era de sonhos e conquistas que ainda ecoa como inspiraço para o futuro.

It will radically change what you thought about wilderness. CAT JARMANA beautiful, deep and grounded book. ALICE ROBERTS When was Britain last truly wild? And what, if anything, remains? This is the unexpectedly human history of wild Britain. In Wilderlands, archaeologist Eloise Kane unearths 12,000 years of our changing relationship with and influence on the landscape. Through prehistory, Roman occupation, the Middle Ages and beyond, we see the unfamiliar beasts of our old wild make way for species such as brown hare and fallow deer, now romanticised as eternal symbols of the British countryside, but introduced much later than we might think.Places free from our influence havent existed for a very long time. But Eloise Kane invites us to rethink our definition of the wild - not as separate from us. Seen anew as the result of millions of human lives lived, Wilderlands demonstrates how we are integral to the ecology and biodiversity of our land - with the power to shape its future.

"Diário de um feio recém-divorciado" é a narrativa engraçada, ácida e, ao mesmo tempo, sensível de um divórcio. Claro, de um divórcio visto pelos olhos de um homem que tenta sobreviver ao maior cataclismo de sua vida com a ajuda pouco confiavel dos amigos e um bom senso de humor, mas amor... Infelizmente, e muito dificil escapar do amor.

Todays computer scientists play the same role as the oracles of the ancient world and the astrologers of the Middle Ages. Modern predictions not only advise on war, crop output, and marriages, but algorithms and statisticians also now determine whether we can get a loan, a job, an apartment, or an organ transplant. And when we cede ground to these predictions, we lose control of our own lives.In this powerful, refreshing new look at the many ways prediction shapes our everyday lives, University of Oxford professor Carissa Veliz explains how putting too much stock in others predictions makes us vulnerable to charlatans, con artists, dubious technology, and self-deception. Examining a wide range of subjects both personal and societal, including medicine, climate, technology, society, and others, Veliz uncovers a number of insights: predictions about humans tend to be self-fulfilling; more data doesnt guarantee better outcomes; AI is more likely to increase risk than decrease it; and a free and robust society requires not more prediction, but better preparation.Veliz argues in this incisive and bracingly original book that the main promise of prediction is not knowledge of the future, but rather power over others. Prophecy is an invitation to defy those orders and live life on our own terms.

A powerful debut compelled by questions of borders and displacement. In one story I stay in that city forever, in one I board, and in another I am still waiting.I am daybreak; I am everywhere.In The Tree Is Missing, Shannon Kuta Kelly explores the poetics of the border. The collection crosses through non-places, moving between the unnamed and unmapped spaces on the edges of the European city. With remarkable poise and restraint, these itinerant poems experiment with oral history and translation, traversing the borderlines of nation, language and time. They draw on folklore to evoke a world that feels current and present, but which can only be reached through storytelling. In doing so, Kuta Kelly explores the loss and displacement - the fracture of identity - necessitated by personal and political turmoil. She writes with a restless immediacy from within the histories that continue to shape us.

FROM THE INTERNATIONAL BESTSELLING AUTHORLeila Slimani has a knack for breaking taboos.TIMESSlimani is a fearless writer.EVENING STANDARD Q: If your house was burning down, what would you take with you?A: Id take the fire.This is the story of two sisters, Mia and Ines. Two girls enveloped in love, trapped by the social conventions of Casablanca at the dawn of the twenty-first century and silenced by the political truths that envelop their lives.Mia - the eldest, a warrior and a pariah, her sexuality a matter of scorn, something to be erased.Ines - the youngest, a woman trying to carve out an identity in a Paris that derides and erases her, with no way back to Morocco, a homeland to which her father has warned her never to return, for her own sake.As these sisters struggle to find a home - a place of safety and love that holds rather than binds - their lives as framed by their mothers and grandmothers before them will be a battle for their hearts and souls, and one they take on with every sinew of their being.We feel deeply for the family caught in the middle of the conflict of history.
