London, Jonathan Cape, 1976. First edition. What if there were a new fuel source made from sweet potatoes? What if the chemist who discovered this died before he could bring the formula to market? What if the race was on to own and control this revolutionary fuel? How would the fossil fuel companies react? In part based on fact, author Davidson brings us a gripping tale as relevant today as it was when it was written. Binding a bit loose in spots, boards very slightly bowed. Attractive price clipped DJ with slight wear to extremities. $35.00.
