Author Doug Fine embarks on a humorous yet rigorous journey to meet the men and women who are testing, researching, and pioneering hemp's applications for the twenty-first century. From Denver, where Fine hitches a ride in a hemp-powered limo; to Asheville, North Carolina, where carbon-negative hempcrete-insulated houses are sparking a mini housing boom; to Manitoba where he raps his knuckles on the hood of a hemp tractor; and finally to the fields of east Colorado, where practical farmers are looking toward hemp to restore their agricultural economy - Fine learns how eminently possible it is for this misunderstood plant to help us end dependence on fossil fuels, heal farm soils damaged after a century of growing monocultures, and bring even more taxable revenue into the economy than its smokable relative.
