After reading a few of Sherrilyn Kenyon’s books, I am amazed how this case even got to court. Cassandra Clare did not plagiarize.
First of all the claim that the dark hunters are basically shadowhunters is bogus. The dark hunters do protect humans from dark forces, but that is where the similarities end. Dark hunters are like vampires. They are immortal, have pointed teeth and sunlight will kill them.
Next, they did not arise from angels as shadowhunters did. Her stories are mainly centered around Greek mythology, and dark hunters arose from Artemis. They didn’t drink from a cup, they gave their souls away.
