And yet there is a degree to which […] all literature, highbrow or low, from the Aeneid onward, is fan fiction. […] Through parody and pastiche, allusion and homage, retelling and reimagining the stories that were told before us and that we have come of age loving — amateurs — we proceed, seeking out the blank places in the map that our favorite writers, in their greatness and negligence, have left for us, hoping to pass on to our own readers — should we be lucky enough to find any — some of the pleasure that we ourselves have taken in the stuff we love: to get in the game. All novels are sequels; influence is bliss.
