Michael C. Grumley

Michael Grumley writes thrillers built around one obsession: stories that actually move. Complex plots, deeply human characters, and endings that will blindside you — every time. His novels Breakthrough, Rollback, and The Last Monument are the result of years spent figuring out exactly how his kind of thriller should be written.

He lives in Northern California with his two daughters, who keep him far too busy and whom he wouldn't trade for anything. When he's not writing or running, he's probably reading.

In the meantime, the next Rollback story is underway. You've been warned.
