Everybody knows CenSecs are the galaxy's deadliest killers. So enhanced that their emotions are dampened to nothing. But Xenia's been keeping a secret her entire life--her systems don't work and she feels. Working with Axton to find the Codex Da Vinci, he makes every emotion in her flare to brilliant life, but to be the perfect CenSec, she must not succumb.
As they follow a trail of clues and booby traps, Axton vows to do everything he can to show his beautiful cyborg the pleasure she's never experienced. Even if she fights him every step of the way. But as the hunt takes a deadly turn, their desire might be the only thing that can save Xenia from annihilation.
