Note: For the purpose of this blog, I'm defining modern as written in the 20th century or later. 
Honorable Mention: Rebecca by Daphne du Maurier (1938)
Rebecca is the oldest book on this list and, in my opinion, can be considered a classic gothic tale just as much as a modern one. I have included it on this list for two reasons. First, it is amazing and needs to be read. Second, there's a new film interpretation coming out starring Lily James and Armie Hammer and you will definitely want to read this before seeing it.
