The Departed writer has signed on for Atlas Entertainment's thriller, reports Deadline.
Plot details are being kept under wraps for Monahan's directorial follow-up to London Boulevard, with production tipped to begin in Southern California this August.
Mojave will be the fourth project for Atlas Independent, an offshoot of Dark Knight producer Charles Roven's Atlas Entertainment.
"Working with Chuck Roven and Atlas is perfection from my point of view, and has already led to a brilliant ongoing relationship," Monahan said.
"It's the strongest possible company and they're specifically in the business of protecting quality work. Atlas and I have decided to do a lot of work together and here we go."
Roven is currently working on The Dark Knight Rises and Superman movie Man of Steel.
