A unique observation that I have made about Sierra’s haiku is the contrasting subject matter that which she writes about, no subject seems to be taboo, and the level of seriousness or lightheartedness ranges in each. Her poems can paint a trashy picture, such as:
drunk girl squats
in the street
or touch you with moving irony:
across the street
great grandma's funeral
You will never know exactly what to expect of the way the world is seen from her eyes, and that makes Sierra’s haiku writings truly something to anticipate.
