I've just discovered two new online journals: Pank and > kill author. I tend to be a little leery about new journals (> kill author is less than 6 months old), but the stories I read in issue 2 were terrific.
Two I especially liked were:
Roxane Gay's Important Things to Know About Career Girls
Lauren Becker's Boilerplate
The other journal, Pank, is out of Michigan and for some reason I thought this was a journal where editors of other journals submitted stories for publication. Not so! Check out Steven McDermott's Sliver -- crisp, fresh prose; engaging. Terrific.
