Within the Folds is a 70,000 word novel where prehistory and the near future meet together in a narrative examining the forces of evolution and duration. The work particularly focuses on the conceptual changes taking place in parenting models as biomedical science gives opportunities to reproductive paradigms which were previously impossible. Taking the premise that developments in human engineering are unstoppable, I explore the transgenic boundaries between 'natural evolution' and proactive human design, conceptually and thematically, as new models of gender roles within family life become inevitable.
