While Hurricane Katrina’s baleful eye bores down on the Gulf Coast and newscasters call for mass evacuation, predicting inundation of New Orleans, time pauses for Louis Proby. Perceiving the irony of fate, Louis remembers another calamity: the 1927 flood when “men with money and the power to change things” persuaded Louisiana’s governor to order the levee protecting his home town, Cypress Parish, dynamited to save New Orleans.

The weather reports fade to the background as Louis opens a binder containing his research of Cypress Parish’s natural history. He recalls his youthful innocence and idealism, and their loss before his 17th birthday — all part of life before the flood. But, mostly Louis remembers loving Nanette Lancon.

Blackwell’s literary novel, The Unnatural History of Cypress Parish, is based on fact. She credits John M. Barry’s Rising Tide, and her grandfather’s unpublished memoirs as history sources for her narrative that examines the poor and powerless of Cypress Parish pitted against the rich and powerful of New Orleans at the approach of impending disaster. “If you want to understand how something works… threaten that society… and its true nature will reveal itself,” writes Barry. That hypothesis is the core of Blackwell’s Cypress Parish.

Louis Proby narrates a dismal reality of people living in dirt poverty compounded by instinctive shame in "where they came from.” He tells of “men whose names mattered before the flood” inviting him to their world of money and power; a world of uneducated men wise in wisdom gained from experience; and a world of racism and hard-won friendship. He tells of his family and the parish people whose lives were changed forever — disrupted by the flood.

Blackwell’s literary gift lies in her ability to create a sense of place that comes from growing up “south of south” in Louisiana. Louis explains, “Who I am remains intimately gnarled with where I came from.” He sees himself and the land as one, “marked by the conditions where the tree was grown.” Elise Blackwell’s writing is steeped in the same rich soil.

The cypress tree symbolizes the parish and Blackwell’s themes of loss, destruction and life disrupted by man’s short-sighted intervention. Louis says: "The most important thing I had written, I understood, was that the bald cypress could live three-thousand years. It takes more than a century for a cypress tree to mature enough to produce good lumber; today cypress is mostly harvested young and sold as mulch."
