A couple anthologies to look out for. One is free, and includes 101 works of flash fiction from 101 authors. It’s called STORIES ON THE GO. A lot of people put a lot of effort into compiling and editing this work. I’m not one of them. All I did was contribute a piece for the collection.
Each story is less than 1,000 words long, so quick reads. This is a great collection of writers and a nice way to discover interesting voices before hunting down more of their works.
