Two soulmates embark on an around-the-world journey, leaving the security of their well-ordered lives in search of larger truths.

Forty-seven years ago, Michael discovered his soulmate Deborah on a dance floor in Keene, New Hampshire. It took her soul a few years and an around-the-world bike trek to fully reciprocate. Riding the Edge is the astonishing tale of the six-month odyssey that profoundly shaped the next 564 months of their lives together.

Taking place in 1980, Michael and Deborah—an American Jew and American Arab, respectively—leave the security of their well-ordered lives as psychologists sleepwalking toward marriage and family to explore and take risks in search of life’s larger truths. What they find is a story of magnificent vistas and memorable moments that enliven their senses to the beauty of the world even as it also reveals the vilest of human cruelty. Simple meals become transcendent experiences and chance encounters are serendipitous markers along a road directing them toward personal and spiritual transformation. Each place leaves its mark—Paris and the French countryside, Italy, Greece, war-torn Beirut, Israel—and each person an imprint even as Deborah and Michael struggle to find the truth of their love. Will they find a life partner or merely a stepping-stone to another, deeper connection?

It’s a journey that has a mind and heart of its own. In the end, each story, kindness, and cruelty uncover the humanness that connects all living things and shows that love is a powerful, healing life force.
