Nice, flowing dialogue (PROSE?) and scenes (STRUCTURE?) A clear picture they bring to your imagination. (CLARITY?) The hook of the two main characters, (CHARACTERIZATION?) but let's face it, if you don't feel anything for the characters, (EMOTION?) the book is pointless.
Writers of sentences whose beauty makes me weep with jealousy. Like Salman Rushdie.
(I hope the plot first brigade won't do me for this. They seem like a feisty bunch.)
