From the Harper Voyager Website:
For the first time in over a decade, Harper Voyager are opening the doors to unsolicited submissions in order to seek new authors with fresh voices, strong storytelling abilities, original ideas and compelling storylines. So, if you believe your manuscript has these qualities, then we want to read it!
We’re seeking all kinds of adult and young adult speculative fiction for digital publication, but particularly epic fantasy, science fiction, urban fantasy, horror, dystopia and supernatural.
They are accepting submissions only from Oct. 1 to Oct. 14. Details on their Website. Good luck! – Meg
