    Prize winning novelist and poet Leona Gom departs from her previous books and challenges the reader to meet an all women society of the future Taught and gripping a page turner at its very best The Y Chromosome examines the reliations and value system of a culture of women where the few men still alive are in hiding socialized early in life to regard themselves as inferior This futurist society abhors its ancestry a male dominated world where violence was commonplace But Gom's woman's universe is far from perfect Avoiding caricatures and easy answers The Y Chromosome is an ironic and provocative novel which probes women's and men's lives in a society which despite striking differences bears many similarities to our world today
