Adam von Gootkin, co-founder of Onyx Moonshine and entrepreneur, wrote “Living Proof: Onyx Moonshine’s Journey to Revive the American Spirit,” which is expected to arrive on store shelves around the country this fall, including Barnes & Noble bookstores. The book chronicles business principles and life lessons gleaned from von Gootkin’s personal experiences while growing a small business into a multi-million dollar, award-winning spirits company. Mike Ditka, the famed former American football player, wrote the forward to the book. The book is available on both Barnes & Noble’s and Amazon’s websites.
