To enter, in a nutshell, you must be a SCBWI member at the time you submit and when the award is announced.
You may not have any works published or under contract with a traditional publishing house, although pre-published and self-published authors are eligible.
It must be a middle grade or young adult manuscript.
The MS must be speculative fiction: "The speculative fiction umbrella covers high fantasy as well as sci-fi, magical realism, fabulism, folklore, horror, alternate history, and other related categories."
Follow the submission guidelines carefully, as they're a bit different than I've seen in other contests, but we all know each is specific.
You need a cover page with a 250-word synopsis and the first 10 pages of your manuscript, attached to an email in a pdf.
The winner "will receive tuition to the Los Angeles Summer Conference (beginning in 2020), a manuscript consultation at the conference, and $300 cash."
If you apply, let me know! I'll cheer for you. Good luck!
