Various biographical and critical pieces by and about Herbert have been collected in "James Herbert: By Horror Haunted", edited by Stephen Jones, and also in "James Herbert – Devil in the Dark", written by Craig Cabell. Herbert released a new novel virtually every year from 1974 to 1988, wrote six novels during the 1990s and released three new works in the 2000s. "I am very insecure about being a writer", he stated in the book "Faces of Fear". "I don't understand why I am so successful. And the longer I stay that way, the better it's going to be, because that's what keeps me on the edge, striving if you like." Herbert's final novel has an eerie political edge. "Ash" imagines Princess Diana and her secret son as well as Lord Lucan, Colonel Gaddafi and Robert Maxwell living together in a Scottish castle. He was the subject of a This is Your Life programme in 1995, when he was surprised by Michael Aspel at the London Dungeon. "Herbert was by no means literary, but his work had a raw urgency," said Stephen King. "His best novels, "The Rats" and "The Fog", had the effect of Mike Tyson in his championship days: no finesse, all crude power. Those books were best sellers because many readers (including me) were too horrified to put them down." "There are few things I would like to do less than lie under a cloudy night sky while someone read aloud the more vivid passages of "Moon,"" Andrew Postman wrote in "The New York Times Book Review." "In the thriller genre, do recommendations come any higher?"
