From their website:
... Starting October 12, Lee Harris and Carl Engle-Laird will be reading and evaluating original novellas submitted by hopeful authors to http://submissions.tor.com/tornovellas/. You can find full guidelines here, and we highly recommend you read the guidelines before submitting. We will be open for three months, beginning on October 12th around 9:00 AM EDT (UTC-4:00) and ending on January 12th around 9:00 AM EST (UTC-5:00). We may extend this period depending on how many submissions we receive over the course of the open period.
Until the end of this open period, Tor.com will only be considering novellas of between 20,000 and 40,000 words that fit the epic fantasy, sword and sorcery, high fantasy, or quest fantasy genres, whether set on Earth or on an original fantasy world. However, we will only be considering novellas that inhabit worlds that are not modeled on European cultures. We are seeking worlds that take their influences from African, Asian, indigenous American, or Pacific cultures, or any diasporic culture from one of those sources. To qualify, novellas should center the experiences of characters from non-European-inspired cultures.
Both Lee Harris and Carl Engle-Laird actively request submissions from writers from underrepresented populations. This includes, but is not limited to, writers of any race, gender, sexual orientation, religion, nationality, class and physical or mental ability. We believe that good science fiction and fantasy reflects the incredible diversity and potential of the human species, and hope our catalog will reflect that.
