THE AWARD-WINNING INTERNATIONAL BESTSELLER by Edith Eger, as seen on BBC Breakfast Even in hell, hope can flower 'One of those rare and eternal stories you don't want to end and that leave you forever changed' - Desmond Tutu 'A masterpiece of holocaust literature. Her memoir, like her life, is extraordinary, harrowing and inspiring in equal measure' - The Times Literary Supplement 'I can't imagine a more important message for modern times. Eger's book is a triumph' - The New York Times 'Little dancer', Mengele says, 'dance for me' In 1944, sixteen-year-old ballerina Edith Eger was sent to Auschwitz. Separated from her parents on arrival, she endures unimaginable experiences, including being made to dance for the infamous Josef Mengele. When the camp is finally liberated, she is pulled from a pile of bodies, barely alive.
The horrors of the Holocaust didn't break Edith. In fact, they helped her learn to live again with a life-affirming strength and a truly remarkable resilience.
The Choice is her unforgettable story. It shows that hope can flower in the most unlikely places.
In 2015 Sheryl Sandberg's husband, Dave Goldberg, died suddenly at the age of forty-eight. Sandberg and her two young children were devastated, and she was certain that their lives would never have real joy or meaning again.
Just weeks later, Sandberg was talking with a friend about the first father-child activity without a father. They came up with a plan for someone to fill in. 'But I want Dave,' she cried. Her friend put his arm around her and said, 'Option A is not available. So let's just kick the shit out of Option B.' Everyone experiences some form of Option B. We all deal with loss: jobs lost, loves lost, lives lost. The question is not whether these things will happen but how we face them when they do.
Thoughtful, honest, revealing and warm, OPTION B weaves Sandberg's experiences coping with adversity with new findings from Adam Grant and other social scientists. The book features stories of people who recovered from personal and professional hardship, including illness, injury, divorce, job loss, sexual assault and imprisonment. These people did more than recover-many of them became stronger.
OPTION B offers compelling insights for dealing with hardships in our own lives and helping others in crisis. It turns out that post-traumatic growth is common-even after the most devastating experiences many people don't just bounce back but actually bounce forward. And pre-traumatic growth is also possible: people can build resilience even if they have not experienced tragedy. Sandberg and Grant explore how we can raise strong children, create resilient communities and workplaces, and find meaning, love and joy in our lives.
'Dave's death changed me in very profound ways,' Sandberg writes. 'I learned about the depths of sadness and the brutality of loss. But I also learned that when life sucks you under, you can kick against the bottom, break the surface and breathe again.
An elegant, thoughtful book . . . beautifully expresses the importance and experience of liberation from the battery-hen life of constant connection and crowds.' Daily Mail 'A compelling study of the subtle ways in which modern life and technologies have transformed our behaviour and sense of self.' Times Literary Supplement In a world of social media and smartphones, true solitude has become increasingly hard to find. In this timely and important book, award-winning writer Michael Harris reveals why our hyper-connected society makes time alone more crucial than ever. He delves into the latest neuroscience to examine the way innovations like Google Maps and Facebook are eroding our ability to be by ourselves. He tells the stories of the remarkable people - from pioneering computer scientists to great nineteenth-century novelists - who managed to find solitude in the most unexpected of places. And he explores how solitude can bring clarity and creativity to each of our inner lives. Urgent, eloquent and beautifully argued, Solitude might just change the way you think about being alone.
'Speaks to a long-overdue conversation we still haven't properly had in our society.' Vice 'A timely, elegant provocation to daydream and wander.' Nathan Filer, author of The Shock of the Fall 'The leading thinker about technology's corrupting influence on our collective psyche.' Newsweek 'A poetic, contemplative journey into the benefits of solo sojourning.' Elle

We are all trapped by modern life. Trapped! Trapped by work, consumerism, stress, debt, isolationism and general unhappiness.
We will each spend an average of 87,000 hours at work before we die. We will spend another 5,000 hours getting to and from work and countless more preparing for work. Worrying about work. Recovering from work.
The majority of us hate our jobs. But without work, we can't buy all the things we've been told we should want and need, so around we go...
Through the pages of New Escapologist magazine, Robert Wringham has been studiously examining the traps of modern life, questioning where our commitment to them stems from and why we are so unable to break free.
Taking inspiration from the great Escapologist Harry Houdini - who escaped from jail cells, straitjackets, and even the innards of a dead whale - Wringham applies Houdini's feats as a metaphor for real life, proposing the principle of Escapology as a way to cut loose our shackles.
Become a modern-day Escapologist and freedom and happiness might be possible after all.

There is a myth in our culture that to find meaning you have to travel to a distant monastery or wade through dusty volumes to figure out life''s great secret. The truth is, there are untapped sources of meaning all around us: right here, right now. Drawing on the latest research in positive psychology; on insights from George Eliot, Viktor Frankl, Aristotle, the Buddha and other great minds, Emily Esfahani Smith identifies four pillars upon which meaning rests: Belonging, Purpose, Storytelling and Transcendence. She also explores how we can begin to build a culture of meaning into our families, our workplaces and our communities. Inspiring and full of contemporary examples, The Power of Meaning will strike a profound chord in anyone seeking a richer, more satisfying life.
