In the sweltering heat of an Arizona July, the desert keeps its secrets. But Cole Harper is about to dig them up.
Cole Harper is barely holding it together. Living in Apache Junction on a diet of Coors Light, beef jerky, and painkillers for a shattered knee, the last thing the veteran PI needs is a complicated case. But when Rachel Simmons-a woman on the run from her corrupt Paradise Valley past-shows up hiding a stolen flash drive, Cole is dragged into a deadly conspiracy.
The drive contains the keys to a massive, dirty land development deal orchestrated by the untouchable Warren Croft. To expose the truth, Cole has to assemble a fractured team: his old ally Kowalski, a relentless corporate researcher named Lucia, and an arrogant, reclusive hacker known only as Virus, who is tasked with doing the impossible-cracking Croft's air-gapped Black Room server.
But Croft has a ruthless fixer named Dale Pruitt, and Pruitt is already on their trail. As the violence spills out across the scorching Sonoran desert and reaches Kowalski's secluded camp at Roosevelt Lake, Cole realizes the price of this case is going up. Outgunned and running out of time, Cole must navigate a broken system to protect Rachel and expose Croft's empire before they are all permanently silenced.
The Math Never Worked is a gritty, atmospheric, hardboiled thriller about corruption, loyalty, and the permanent costs of doing the right thing.
