For obvious reasons, the relationship between novelists, the reviewing establishment and critics in general is chronically, and often acutely, edgy. A kind of low-intensity warfare prevails, with outbreaks of savagery. It is partly an ownership issue. Who, other than its creator, is to say what a work of fiction means or is worth? It can take years to write a novel and only a few hours for a critic, or a reviewer rushing for a tight deadline, to trash it.
