A.G. Riddle spent ten years starting internet companies before retiring to pursue his true passion: writing fiction.

His debut novel, The Atlantis Gene, is the first book in a trilogy (The Origin Mystery) that has sold over three million copies worldwide, has been translated into twenty-four languages, and is in development to be a major motion picture.

His fourth novel, Departure, follows the survivors of a flight that takes off in 2015 and crash-lands in a changed world. HarperCollins published the novel in hardcover in the fall of 2015, and 20th Century Fox is developing it for a feature film.

Released in 2017, his fifth novel, Pandemic, focuses on a team of researchers investigating an outbreak that could alter the human race. The sequel, Genome, concludes the two-book series.

Released in 2019, his seventh novel, Winter World, depicts a group of scientists racing to stop a global ice age. It is the first book in The Long Winter Trilogy, which is now complete.

Riddle grew up in Boiling Springs, North Carolina and graduated from UNC-Chapel Hill. During his sophomore year in college, he started his first company with a childhood friend. He currently lives in Raleigh, North Carolina with his wife, daughter, son, and an eccentric dog.
