Belladonna Nightshade - Charity Anthology Call

Belladonna Nightshade has posted an anthology call for "Mars Needs Writers".  They are looking for stories of 2000 to 10,000 word (prefer 5000 to 7500) using the theme of The Red Planet.  Any speculative fiction genre is welcome.  Stories should be PG as they're also asking for young people to write for this anthology.  Reprints are okay.  The deadline is October 12, 2018.  There is no payment as this is a charity anthology with proceeds going to the Challenger Center's Martians of Tomorrow STEM education campaign.  You can find the details here.
