In the not-so-distant future, economic inequality and persistent surveillance push Oakland to the brink of civil war. Lilly Miyamoto is a passionate analog photographer striving to pursue an ever more distant dream. Huian Li is preeminent among the Silicon Valley elite as the founder and CEO of the pervasive tech giant Cumulus. Graham Chandler is a frustrated intelligence agent forging a new path through the halls of techno-utopian royalty. But when Huian rescues Lilly from a run-in with private security forces, it sets off a chain of events that will change their lives and the world. The adventure accelerates into a mad dash of political intrigue, relentless ambition, and questionable salvation. Will they survive to find themselves and mend a broken system?

  • “Cumulus is your new favorite surveillance-fueled dystopian novel. It’s a future we can all recognize—and one that we should all be genuinely afraid of.”

    -Ars Technica

  • “An intriguing, fast-paced thriller that looks closely at the most pressing issues facing the nation: a growing wealth gap, corrupt governments and an ever-increasing surveillance apparatus that threatens the country’s very character. Cumulus holds up a mirror to ourselves, and shows just how scary the world could be right around the corner.”


  • “A gritty view of the future of economic inequality and surveillance. In a city divided between the haves and have-nots, anonymity is virtually impossible… except for a few insiders who have the power to subvert the system for their own purposes.”
