She Kills Monsters tells the story of Agnes Evans as she leaves her childhood home in Ohio following the death of her teenage sister, Tilly. When Agnes finds Tilly's Dungeons and Dragons notebook, she stumbles into a journey of discovery and action-packed adventure in the imaginary world that was Tilly's refuge. In this high-octane dramedy laden with homicidal fairies, nasty ogres, and 90's pop culture references, playwright Qui Nguyen offers an homage to the geek and warrior in us all.
