Storm: A Motorcycle Journey of Love, Endurance and Transformationis a story of travel, love, and transformation that unfolds against the promise of a summer spent traveling around the Baltic Sea by motorcycle. Begun as a grand adventure, the trip quickly becomes a tumultuous test of endurance. In the summer of 1993, shortly after the opening of Russia and the Baltic States to travelers, Allen and his girlfriend Suzanne traveled through Germany, Denmark, up the length of Sweden to the Arctic Circle, across Finland, through a portion of Russia, and across the newly opened Baltic States of Estonia, Latvia, and Lithuania, and, finally, Poland. Allen and Suzanne were seasoned travelers, partners for seven years. In the midst of riding through record-breaking storms, traversing a landscape of remote islands and limitless forests, encountering a cast of eccentric characters, and fighting unforgiving elements, their relationship began to erode. As the trip progressed over the Arctic Circle in Sweden, and across the taiga of Finland towards the Russian border, Allen and Suzanne struggled to maintain a sense of purpose and dignity as a couple. And the hardest part still lay ahead.
