Define The Mortal Instruments Meaning

The Mortal Instruments
An absolutely awesome series written by Cassandra Clare. It has everything! (demon fighting, canon slash, technical incest, faeries, werewolves, geeky references, etc.) The Fandom is one of the most perverted ones. We have great fanart. And a duck!

Person A:Have you read City of Bones yet?
Person B: No, I've never heard of it!
Person A: It's the first book in the Mortal Instruments series. I think you would like it!
