Using never before seen sources, Once a King is a fresh, revelatory and gripping insight into the Duke of Windsor - King Edward VIII - who gave up the throne to marry the woman he loved, twice divorced American Wallis Simpson. Considering Edward VIII's travels and interests as Prince of Wales as well as his relationship with Wallis Simpson and the course of events leading up to his abdication and subsequent exile, Once a King offers a previously unexplored lens through which we encounter first-hand the hitherto concealed subtlety and raw emotion of two of the twentieth century's most iconic Royal figures: the Duke and Duchess of Windsor.
