C S Lewis readers will identify the main title of this new book: Melvin Tinker uses Lewis's prescient fiction work as a launchpad for a fascinating look at the rapidly changing worldview of Western civilisation. Too often books dealing with these issues are academically inclined and not accessible by the ordinary reader: that is not the case here. Based on a lecture delivered at GAFCON in June 2018, this book will stimulate thinking and open the eyes of Christians to the dangers of the worldview relentlessly promoted by the media.
