I myself prefer only to read books that have been described as “unputdownable,” but Joe Queenan has his own preferred adjective which appears to be serving him well:
Several years ago, overwhelmed by the flood of material unleashed annually by the publishing industry, I decided to establish a screening program by purchasing only books that at least one reviewer had described as “astonishing.”
Previously, I had limited my purchases to merchandise deemed “luminous” or “incandescent,” but this meant I ended up with an awful lot of novels about bees, Provence or Vermeer.
