When Joe Mayfield’s wife’s HealthScore is slashed, his happy, ordinary life spirals into chaos. Joe’s frantic search to save her makes him a target of Phoenix, one man’s plot to skim billions in medical payments at the cost of thousands of lives. Joe goes off the grid, living on cash in out-of-the-way places, grieving for his wife, and vowing to expose Phoenix. He hacks into the national database called the Yak, drawing the interest of a brilliant Yak tracker called Weezy. She runs him down, ultimately becoming an ally. Finally, in a single wide trailer in Panacea, Florida, Joe and Weezy work to destroy Phoenix before Phoenix destroys them.
