Described as

“…one-part story and one-part poem. Plot matters less than mood and telling details—yet it does matter. The joy of flash fiction as a writer and a reader is found not only in the words of the story, but in what is left out—the absences can be almost spectral, haunting what’s been told, only guessed at.”  
(Editor/Writer, Grant Faulkner)

“…a genre that is deceptively complex.”
(Becky Tuch, writer for the review, views on publishing) 

“…the intellectually challenging blurb… [but] …do not make the mistake of assuming that such bare-bones writing is less than elegant or beautiful. Flash fiction is a story in which every word is absolutely essential, …peel away the frills and lace until you’re left with nothing but the hard, clean-scraped core of a story.” 
(Jason Gurley, writer for Writing-World.com) 

“… fictional work of extreme brevity, that still offers character and plot development. Possess[ing] a unique literary quality, e.g., the ability to hint at or imply a larger story.”
