Joe Mayfield's happy, ordinary life comes apart when his wife's HealthScore is slashed and she is denied cancer treatment. Frantic to save her, Joe hacks into the Yak -- the national database the US created after CyberWar I. Joe's discovery makes him the 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. Weezy, a brilliant Yak tracker runs him down, assuming he's a black hat hacker. She becomes Joe's ally when Phoenix targets her. Finally, in a single wide trailer in Panacea, Florida, Joe and Weezy work to destroy Phoenix before Phoenix destroys them. Fatal Score is a debut novel about big data, the future of medicine, the pain of loss, and the power of redemption.
