See my latest contest roundup for Writer Unboxed:
This submissions season covers deadlines from December 1, 2018 through February 28, 2019. Don’t let your words wither on your hard drive! Finish the year strong by sending out your best work and start the new year with an invigorating round of submissions. Thanks to Literistic, Poets & Writers, Submittable Discover, and New Pages for many of these contests.
I found 20+ opportunities for emerging and established fiction writers. Each comes with its own handy list of reasons to submit. See my roundup of Winter 2018 writing contests.
