A former entertainment journalist, she transitioned to fiction with 2007’s genre-defining *City of Bones* (Mortal Instruments series), establishing her signature mix of mythos-driven plots and character-driven drama. Her expanding catalog includes the Victorian-era Infernal Devices trilogy and the Dark Artifices series, both exploring themes of heritage and sacrifice across generations.
