Book Four of Five is the latest collection of five gripping short stories from prolific author David Hughes. Once again, he has written stories that will keep the reader speculating on the subject, with plot lines that compel you to think about life and consider the foibles and habits of the general public. Our way of life has developed year on year - sometimes the changes are improvements and sometimes they can be detrimental to society at large. Science has made huge leaps forward, with technology giving even the most ordinary person the capability to bring about catastrophic events, as can be seen in ‘Liquid Oxygen’. In another story, genetics, the study of heredity, and the biological process where a parent passes certain genes onto their children is featured - along with the hazards of making friends at university and work in others. Who would guess that everyday life could be so perilous!
