Book excerpt: When entrepreneur Len Forkas learned that his nine-year-old son had leukemia, his own life changed forever. In 2003, Len founded Hopecam, a nonprofit that uses technology to connect young cancer patients with their friends at school. Ten years later, Len's fight against childhood cancer rose to a new level. He qualified as a solo competitor in Race Across America, a 3,000-mile bicycle race that traverses scorching deserts and 11,000-foot mountain elevations. As Len fought to finish the race is just 12 days, an all-volunteer crew supported him around the clock. What Spins the Wheel is a true story about fatherhood and fortitude, business grit and growth - and the power of combining the right mission with the right team to help others.
