Reissue of J. A. Baker’s extraordinary classic of British nature writing Despite the association of peregrines with the wild, outer reaches of the British Isles, The Peregrine is set on the flat marshes of the Essex coast, where J A Baker spent a long winter looking and writing about the visitors from the uplands – peregrines that spend the winter hunting the huge flocks of pigeons and waders that share the desolate landscape with them. Including original diaries from which The Peregrine was written and its companion volume The Hill of Summer, this is a beautiful compendium of lyrical nature writing at its absolute best. Such luminaries as Richard Mabey, Robert Macfarlane, Ted Hughes and Andrew Motion have cited this as one of the most important books in 20th Century nature writing, and the bestselling author Mark Cocker has provided an introduction on the importance of Baker, his writings and the diaries – creating the essential volume of Baker's writings. Since the hardback was published in 2010, papers, maps, and letters have come to light which in turn provide a little more background into J A Baker’s history. Contemporaries – particularly from while he was at school in Chelmsford – have kindly provided insights, remembering a school friend who clearly made an impact on his generation. In the longer term, there is hope of an archive of these papers being established, but in the meantime, and with the arrival of this paperback edition, there is a chance to reveal a little more of what has been learned. Among fragments of letters to Baker was one from a reader who praised a piece that Baker had written in RSPB Birds magazine in 1971. Apart from a paper on peregrines which Baker wrote for the Essex Bird Report, this article – entitled On the Essex Coast – appears to be his only other published piece of writing, and, with the kind agreement of the RSPB, it has been included in this updated new paperback edition of Baker’s astounding work.

Dead cats. That's the image many people conjure up when you mention curiosity. An image perpetuated by a dusty old proverb that has long represented the extent of our understanding of the term. This book might not put the proverb to rest, but it will flip it upside down: far from killing anything, curiosity breathes new life into almost everything it touches.In CuriousDr. Todd Kashdan offers a profound new message missing from so many books on happiness: the greatest opportunities for joy, purpose, and personal growth don't, in fact, happen when we're searching for happiness. They happen when we are mindful, when we explore what's novel, and when we live in the moment and embrace uncertainty. Positive events last longer and we can extract more pleasure and meaning from them when we are open to new experiences and relish the unknown.Dr. Kashdan uses science, story, and practical exercises to show you how to become what he calls a curious explorer a person who's comfortable with risk and challenge and who functions optimally in an unstable, unpredictable world. Here's a blueprint for building lasting, meaningful relationships, improving health, increasing creativity, and boosting productivity. Aren't you curious to know more?

In the critically acclaimed memoir Girl Meets God, Lauren F. Winner chronicled her sojourn from Judaism to Christianity. Now, in Still: Notes on a Mid-Faith Crisis, Winner describes how experiences of loss and failure unexpectedly slam her into a wall of doubt and spiritual despair: My belief has faltered, my sense of God’s closeness has grown strained, my efforts at living in accord with what I take to be the call of the gospel have come undone.”Witty, relatable, and fiercely honest, Winner lays bare her experience of what she calls the middle” of the spiritual life. In elegant and spare prose, she explores why in the midst of the overwhelming anxiety, loneliness, and boredom of her deepest questioning about where (or if) God is the Christian story still explains who she is better than any other story she’s ever known. Still is an absorbing meditation combining literary grace with spiritual wisdom. It is sure to resonate with anyone looking to sustain a spiritual life in the midst of real life.

When called upon to explain their faith, Christians do not always feel equipped to do so particularly when some of the most difficult questions arise. In The Allure of Gentleness, esteemed teacher and author Dallas Willard not only assures us of the truth and reasonableness of the Christian faith, but also explores why reason and logic are not enough: to explain Jesus's message, we must also be like Jesus, characterized by love, humility, and gentleness.Based on a series of talks and lectures on apologetics given by the late author and edited by his daughter, Becky Heatley, this book constitutes Dallas Willard's most thorough presentation on how to defend the Christian faith for the twenty-first century. This beautiful model of life, this allure of gentleness, Willard tells us, is the foundation for making the most compelling argument for Christ, one that will assure others that the Christian faith is not only true but the answer to our deepest desires and hopes.

In this highly acclaimed translation, Stephen Mitchell conveys in English the simplicity, dignity and powerful earthiness of the original Hebrew. More than just interpreting it, he also separates stories that were combined by scribes centuries after they were written, explaining their sources and omitting all verses that are recognized as scribal additions. Like removing coat after coat of lacquer from a once-vibrant masterpiece, this allows readers to appreciate the clarity of the original tales.Genesis is an extraordinarily beautiful book that is accessible in a way that no other translation has ever been. It will shed new light on readers' understanding of this seminal work of sacred *ure.
