Damian "Vesper" Wolfe is a ghost-an elite killer and master thief who leaves no evidence behind. After two murders, the theft of twelve million dollars, and eight months on the run, he has become the FBI's most wanted fugitive. Every attempt to track him ends in failure as he disappears into the digital world without a trace.
FBI Agent Ethan Carter is running out of time. Despite the Bureau's best cyber investigators, Wolfe continues to outsmart every system designed to catch him. As pressure mounts, the hunt becomes more desperate.
Meanwhile, Maya Collins, a brilliant but unemployed hacker, has no intention of getting involved. But when her best friend, an underfunded police officer, uncovers a crucial lead, Maya uses her own powerful algorithm to find Wolfe before the FBI does. What begins as a no simple favor quickly turns into a deadly race for survival.
Now three forces are closing in on one invisible target. Wolfe is fighting for freedom, the FBI is determined to bring him to justice, and Maya is risking everything to protect the people she loves.
In a city where every move is monitored and every device leaves a trace, one man has mastered the impossible. In a system built to find everyone, the hardest person to catch is the one who refuses to be seen.
