Introduce the story's full title and the name of the author. If the work is part of an ongoing collection, make note of it. If the piece is the author's debut work, this may be noted as well.
Introduce the plot line without giving away the entire story. You may choose to name the main character or note a particularly interesting aspect of the plot.
Provide honest feedback. If there is something you find compelling, make note of it. Be equally mindful of pointing out flaws, though be sure to remain constructive. A review does not have to be all flattery, but you should support your criticisms.
Conclude by noting what the story accomplishes and how everything is tied together for you as a reader.
