He is the author of The Curious Gardender's Almanac and over a dozen other books under a variety of guises and noms de plume, covering military history, biography, sport, general humor, and gardening. He lives in West Sussex with his wife and two children.

The following are the author's biographical blurbs as they appear in The Optimist's/Pessimist's Handbook:

The Optimist's Handbook:
Niall Edworthy is the celebrated author of twenty books, making him a hero to many around the globe. Commentators say it is just a matter of time before he sweeps the board of literary awards, turns down a seat in the House of Lords and retires from his estate in the Home Counties to a tropical island, a robust, over-sexed, eight-figure-millionaire philanthropist.

The Pessimist's Handbook:
Over the past decade Niall Edworthy has made a poor to modest living as a jobbing hack. An ongoing disappointment to his dysfunctional family and both his friends, Niall spends his days in a cold garage in the middle of nowhere typing nonsense into an old computer with the one finger not yet afflicted by RSI. His magnum opus, Life Is a Bowl of Toenail Clippings, remains unfinished.
