As with any Hugo novel, if you come to the book expecting it to be like its adaptations, you will be disappointed—the novel is much more interested in depicting a historical place and time than focusing on a particular character or storyline. The biggest surprise for me (who otherwise by and large knew what to expect from Hugo) was how morally ambiguous every character was. It's fascinating to compare with its adaptations and consider what goals and effects various changes had. 

Also, there's not a specific content warning label for this but I think it's worth noting that this book contains a repeated accusation of blood libel.
