The story of human civilization can be read most deeply in the materials we have found or created, used or abused. They have dictated how we build, eat, communicate, wage war, create art, travel, and worship. Some, such as stone, iron, and bronze, lend their names to the ages. Others, such as gold, silver, and diamond, contributed to the rise and fall of great empires.

As a kid, Nina O'Brien spent all her summers at her grandparents' cabin by the beach at Stepping Stone Bay. Long, sunny days full of fun and laughter with her best friends, Leo, the boy from the boatyard next door, his older brother, Adrian, and local girl Maeve - and, as Nina grew older, the magic of falling in love with Leo. But one summer night changed everything, and those glorious days came to an abrupt end for them all.

The cells were supposed to die. Instead, they changed everything. When Henrietta Lacks walked into Johns Hopkins Hospital in 1951 complaining of vaginal bleeding, neither she nor her doctors could have imagined the medical revolution about to unfold. The cervical cancer that would claim her life at age 31 harbored an extraordinary secret: her cells could live forever. Without her knowledge or consent, those cells would reshape modern medicine. Dubbed "HeLa" cells, Henrietta's tissue became the cornerstone of countless medical breakthroughs.

In 1922, Howard Carter peered into Tutankhamun's tomb for the first time, the only light coming from the candle in his outstretched hand. Urged to tell what he was seeing through the small opening he had cut in the door to the tomb, the Egyptologist famously replied, "I see wonderful things". Carter's fabulous discovery is just one of the many spellbinding stories told in Three Stones Make a Wall.

In Japanese gardens, composition follows from placement of the first stone; all elements and plantings become interconnected. These eight essays on Kyoto gardens similarly begin with keen description and build into richly meditative excursions into art, Buddhism, nature, and science. Landscape architect Marc Keane shows how Japanese gardens are both a microcosm of the natural universe and a clear expression of our humanity, mirroring how we think, worship, and organize our lives and communities.

Stone walls tell nothing less than the story of how New England was formed, and in Robert Thorson's hands they live and breathe. Millions of years ago, New England's stones belonged to ancient mountains thrust up by prehistoric collisions between continents. Buried again over centuries by forest and soil buildup, the stones gradually worked their way back to the surface, only to become impediments to the farmers cultivating the land in the eighteenth century, who piled them into "linear landfills," a place to hold the stones.

Our brains evolved to solve the survival problems of our Stone Age ancestors, so when faced with modern-day situations that are less extreme, they often encounter a mismatch. Our primitive brains put us on the wrong foot by responding to stimuli that - in prehistoric times - would have prompted behaviour that was beneficial. If you've ever felt an anxious fight-or-flight response to a presenting at a board meeting, equivalent to facing imminent death by sabre-toothed tiger, then you have experienced a mismatch.
