 Martin is widely credited with broadening the fantasy fiction genre for adult content, including incest, paedophilia, and adultery.Writing for "The Atlantic", Amber Taylor assessed the novels as hard fantasy with vulnerable characters to which readers become emotionally attached.CNN found in 2000 that Martin's mature descriptions were "far more frank than those found in the works of other fantasy authors", although Martin assessed the fantasy genre to have become rougher-edged a decade later and that some writers' work was going beyond the mature themes of his novels.
