Congratulations to Dr. Conny Burian who has recently published a historical novel in German. It's a fictional autobiography of the woman who may have written the famous Nibelungenlied, a high medieval epic. Dr. Burian based her novel on research that she conducted for a course she teaches for the University of Calgary.
