When Cyrex Corp, one of the foremost bioaugmentation companies in the world, sends Vax to assassinate Zai Lumero, Vax thinks it'll be a simple, straightforward job. Zai is only a journalist, after all, and with his bioaugments, Vax has never botched a job before. But then the hit unexpectedly goes south, and before Vax can correct his mistake and finish Zai off for good, he discovers that Cyrex has turned on him, putting him in their crosshairs as well.

With no one else to turn to, he strikes a grudging partnership with Zai to help him expose Cyrex's connection to a missing persons case and take the company down. Getting along with a justice crusader who hates Vax's profession with a burning passion isn't easy--though Vax finds himself drawn to Zai in a way he never expected.

As they race against time to unearth Cyrex's secrets, Vax can't shake the feeling that Zai is hiding something from him. And the closer he gets to uncovering the answers--of how he's related to Zai's investigation, and how Zai is connected to a past that Vax can't remember--the more he suspects that finding out the truth might destroy him.
