Roberta Beary, award-winning poet and haibun editor of Modern Haiku, the judge of this contest, wrote:
Stella Pierides’ haibun shows how time, which is also the title, turned the narrator’s expectations of her life’s autumn upside-down. The haiku at the haibun’s end effectively juxtaposes the images and original word choice in lines 1 and 2, lulling the reader along until the surprise of line 3. At first glance the haiku does not seem relevant to the prose. A deeper reading shows that the haiku echoes and expands the feelings of surprise and mortality elicited by the prose, which is exactly what is supposed to happen in haibun.
