Computer forensics expert Lucy McCart is called to investigate a high-profile murder and discovers that the elusive killer was paid by thousands of anonymous donors across the dark web. Her efforts are thwarted by untraceable digital currency and uncrackable encrypted communications. Meanwhile, more online assassination markets appear, crowdfunding the murders of crooked politicians, corporate fat cats, and rude movie stars... providing society with the ultimate in "distributed denial of service." As the body count rises, Lucy's father wins reelection to the Senate and is implicated in a horrifying scandal. The public is outraged and he is quickly targeted for death. Can Lucy stop the assassination markets in time to save her father's life?
