From the New York Times bestselling author comes a wondrous, curious journey through the wilds of nature and the gnarls of history, exploring how trees – from the mightiest sequoia to the tiniest bonsai – can teach us to grow wise.

One day, on a whim, Robert Moor set out to climb a tree near his home, unwittingly embarking on what would become a decade-long, globe-spanning adventure in trees. From Darwin to Attenborough, Brecht to Wordsworth, cutting-edge scientists and Zen monks and Bonsai artists, In Trees explores the fundamental and meaningful role of trees in the natural world.

From Ethiopia and Papua to the Sierra Nevada mountains and the Lake District, bestselling author Robert Moor uncovers the hidden art of 'tree-thinking', a powerful tool for approaching humanity's oldest questions: What is the secret to growing old well? How do we set down deeper roots in an increasingly chaotic world? And most importantly, how should we – as individuals, as communities, as stewards of the Earth – live?

Weaving together history, ecology, philosophy, neuroscience, mythology, literature, and the abstract qualities of identity, belonging and memory, In Trees shares extraordinary stories of how trees have become embedded in our culture, lifestyle and imagination for centuries, becoming the key to almost everything on our planet.

What began as an ode to the miracle of trees blossoms into a joyous, daring, fiercely hopeful endeavour that reveals . . . To truly grasp the wisdom of a tree, you need to begin thinking like one.
