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 The Origin Mystery, the trilogy that has sold a million copies in the US, is being translated into 18 languages, and is in development at CBS Films to be a major motion picture. The trilogy will be in bookstores (in hardcover and paperback) around the world in 2015.

His recently released fourth novel, Departure, follows the survivors of a flight that takes off in 2014 and crash-lands in a changed world. The hardcover will be published by HarperCollins in the fall of 2015, and 20th Century Fox is developing the novel for a feature film.
