World Fantasy Award for Best Novella

The World Fantasy Awards are given each year by the World Fantasy Convention for the best fantasy fiction published in English during the previous calendar year. The awards have been described by book critics such as The Guardian as a "prestigious fantasy prize", and one of the three most prestigious speculative fiction awards, along with the Hugo and Nebula Awards (which cover both fantasy and science fiction). The World Fantasy Award—Long Fiction is given each year for fantasy stories published in English. A work of fiction is eligible for the category if it is between 10,000 and 40,000 words in length; awards are also given out for longer pieces in the Novel category and shorter lengths in the Short Fiction category. World Fantasy Award nominees and winners are decided by attendees and judges at the annual World Fantasy Convention.
