Michael Gruber is an author living in Seattle, Washington. He attended Columbia University and received his Ph.D. in biology from the University of Miami. He worked as a cook, a marine biologist, a speech writer, a policy advisor for the Jimmy Carter White House, and a bureaucrat for the EPA before becoming a novelist.

He is generally acknowledged to be the ghostwriter of the popular Robert K. Tanenbaum series of Butch Karp novels starting with No Lesser Plea and ending with Resolved. After the partnership with Tanenbaum ended, Gruber began publishing his own novels under William Morrow and HarperCollins.

Gruber's "Jimmy Paz" trilogy, while critically acclaimed, did not sell at the same levels as the Butch Karp series in the United States. The Book of Air and Shadows became a national bestseller shortly after its release in March of 2007, however.
