I’m not familiar with this market so proceed with caution but Dreaming Robot Press, an indie sci-fi/f publisher for YA and middle-grade readers, is seeking submissions for the 2016 edition of the Young Explorer’s Adventure Guide.
The anthology is a collection of sf/f aimed at a middle-grade and young adult readership with protagonists from 9-12 years old. Stories can include adventure, space, science, rockets, robots, alien encounters, steampunk, time travel, weird west or alternate history. That’s a pretty broad range! If you have a piece that sounds like a good fit and is between 3,000 and 6,000 words, check out their full guidelines here. Don’t delay — you have to email manuscripts to her by Sunday! You submit through a link on the guidelines.
