When our sense of wholeness depends on things or people outside ourselves—whether it's a coveted job, a new house, a lavish vacation, or even a new relationship—sooner or later we're bound to feel unsatisfied. But how do we embark on this inner journey? Living Untethered is the book to reach for. It provides clear guidance for moving beyond the thoughts, feelings, and habits that keep you stuck—so you can heal the pain of the past and let your spirit soar. It's time to stop struggling and start experiencing.

Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide. In this, her first book, now available in audio, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths—that trees are not simply the source of timber or pulp, but are a complicated, interdependent circle of life.

Since she was nine years old, Alina Dziak knew she would marry her best friend, Tomasz. Now 15 and engaged, Alina is unconcerned by reports of Nazi soldiers at the Polish border, believing her neighbors that they pose no real threat, and dreams instead of the day Tomasz returns from college in Warsaw so they can be married. But little by little, injustice by brutal injustice, the Nazi occupation takes hold, and Alina’s tiny rural village, its families, are divided by fear and hate. Then, as the fabric of their lives is slowly picked apart, Tomasz disappears.

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.
