Book excerpt: Meet Chris and Marty—a married couple working on their careers, raising their only child, and chasing big adventures. At midlife, they suddenly find themselves weighing the responsibility of parenthood against the possibility of one more grand adventure, before their aging bodies and the warming continent of Antarctica further degrade. They ultimately decide it’s time to pursue their biggest dream: Ski 570 miles from the edge of Antarctica to the South Pole. With no guide or resupply. From the lush Pacific Northwest to the barren landscape of Antarctica, Chris and Marty embark on one of the hardest challenges on the planet. After three years of intense planning and training, including meticulous preparations for the care of their twelve-year-old son, they are ready. Experience a boundless white wonderland like no other on earth. Encounter life-threatening dangers lurking in the bitter cold. Feel the intensity of 220-pound sleds, relentless wind, 40-below temperatures, and mind-numbing isolation. This is not an average couples getaway. Chris and Marty go where few others have dared on the way to making history—stretching their bodies, minds, and marriage to the limit in the process. Riveting and inspiring, The Expedition is about the power of family and community, the adventurous spirit that dwells within us all, and breaking through to feel fully alive.
