Okonkwo Okuji Awa is a new writer publishing mainly through the print-on-demand medium because of the changing nature of the capital-intensive traditional book publishing methodologies. Interestingly, this procedure was against the grain of advice proffered by a famous African Nobel laureate at the time. In that instance, the currency of empirical research work triumphed over the wisdom of professional experience. The author is an American trained Chemical Engineer and Nigerian Businessman, writing seriously primarily in English but as a hobby. One of my books was exhibited at the 2010 London Book Fair and all copies exhibited were donated to charity. On my wish list is the hope that those who have read or bought my books will return to give my writing a formal rating - instead of by word of mouth. Please note that additional pages of images and commentary are included, as an added bonus, for buyers of the hardcover version of one of my books. Okonkwo Okuji Awa, August 6, 2011
