I love all types of mysteries/thrillers. This genre peaked my interest. I have never read about this type of chromosomal/family/fertility issue. The book has lots of twists and turns and I think I know how it may turn out, but, usually I am surprised at the endings. I will for certain have to find out how this book continues. a fascinating, on the edge of your seat, unfathomable story, that one day may be reality?
