Books like the mortal instruments trilogy

The Mortal Instrumentsis a series of six young adult fantasy novels written by Cassandra Clare, the last of which was published on May 27, 2014.The Mortal Instrumentsis chronologically the third series of a proposed five inThe Shadowhunter Chroniclesbut it was the first one published. It follows Clary Fray (who interacts with a group of Nephilim known as Shadowhunters) while also discovering her own heritage. The Shadowhunters protect the world of mundane people, who are also called mundanes or "mundies", from dark forces beyond their world.

The book series has become one of the most popular within the young adult genre of paranormal romance/urban fantasy, but Clare did not originally intend to write the series for teens. When she began writingCity of Bones, she did not view it as a young adult work, but first and foremost as a fantasy novel, where the main characters just happened to be teenagers. When she was approached by a publisher interested in aging up her characters, she ultimately decided that she "wanted to tell a story about characters at that crucial life stage just between adolescence and adulthood, where your choices determine the kind of person you're going to be rather than reflecting who you already are." The decision to launch her novels as Young Adult books has propelled Clare to the top of the Bestsellers list and has establishedThe Shadowhunter Chroniclesas some of the most popular works read by a largely young adult audience.
