At first glance, there are several components on the poster that seemingly add up to provide a view into the theme of the book. The crown drips with blood, showing me that the book is about royalty and several deaths throughout the piece. The cross on top of the crown, represents religion and Christianity, which would display to me that this takes place in a European or western country. Since the cross is somewhat a significant part of this poster, I would imagine that religion takes a large part of this play and could be notable part of the main conflicts or plot.
