Reddit mentions of Writers of the Future Volume 30

I'm finding them pretty easily for Kindle. Are you accessing Amazon from a different country's domain? That might be the issue. Here's a link to the Kindle version of Vol. 30.

Like /u/PhilosofizeThis said, the stories lean heavily on the genre side, with most being Sci-Fi and Fantasy. Honestly, though, the quality isn't much different than what you'd see in the big SFF magazines such as Lightspeed, Clarkesworld, Analog, Asimov's, etc.

The one difference from the above-mentioned magazines is the length of the stories, though not all of them go up to 17k words. I'd say most are in the 8k-10k range.

Definitely worth reading, especially if you're a short story writer looking to improve.
