I've been reading some horror and dark fantasy short fiction lately,
and then I came across the work of Aris Moore, which struck me as
perfectly dark and subtly horrifying, its cutting, absurd mood the
same as some of the stories I've been reading. Check it out and have
a go at some darker kinds of writing...
And if you want something to read, check out Lisa Tuttle's "Objects
in Dreams May Be Closer Than They Appear," which is very creepy
..found in the House of Fear anthology and The Year's Best Dark
Fantasy & Horror 2012.
