coquel

noun

1. A narrative about events occurring simultaneously with events of another narrative on which it is based.

   “We might also consider adaptation alongside the processes of publishing sequels, prequels and coquels, and fan fiction.”

   “A whole constellation of terms such as prequel, coquel and sequel, that have been designed to account for the many, endless rewritings of books like Jane Eyre or Dracula, goes some way towards establishing this never-ending process of literary mutations, pre-empting the possibility of closure.”

   “Yet more recent, and possibly still a neologism, is the word "coquel", which like "prequel" is adapted from "sequel" with a prefix that indicates its temporal relation to the plot of the source: coquels evoke events that are simultaneous with the source text.”
