The Mortal Instruments is a series of young adult fantasy novels written by American author Cassandra Clare, the last of which was published on May 27, 2014. The Mortal Instruments is chronologically the third series of a planned five in The Shadowhunter Chronicles but it was the first one published. It follows Clarissa Fray while also discovering her own heritage and her family history. The Shadowhunters protect the world of mundane/human people, who are also called mundanes or "mundies", from dark forces beyond their world.

The book series has become popular within the young adult genre of paranormal romance/urban fantasy and supernatural, but Clare did not originally intend to write the series for teens. When she began writing City 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 inspiration for Netflix's hit show Shadowhunters, Cassandra Clare's Mortal Instruments series combines heart-stopping, action-packed thrills with supernatural elements and forbidden romance. Complete with refreshed artwork, here you'll find all six books in the series for one unbelievable price.

Featuring mature themes throughout, these books are ideal for teens who love The Hunger Games and The Maze Runner. The series starts with City of Bones, a novel that introduces the heroine, 16-year-old Clary Fray, and explains how she's starting to see things she shouldn't - including vampires in Brooklyn and werewolves in Manhattan.

After witnessing a horrific incident, Clary finds herself drawn to the Shadowhunters, a secret group who are determined to rid New York's underworld - and the rest of the world - of demons. Full of mystery, intrigue and betrayal, Clary also finds herself falling for someone she shouldn't...
