Tin Man

Officer Adam "Lemon" Lehmann volunteered for experimental cybernetic upgrades to save his life, but the decision killed his career. Now working as a bar bouncer in a society which both fears and loathes cyborgs, Adam wants to lay low until either his aging human parts, or his glitching cyborg parts end his lonely life.
Eve Myer has critical information about her employer's corporate corruption which is killing cyborgs. But when the internet whistleblower she meets at a bar takes a fatal shot meant for her, she clings to the sexy yet reticent bouncer's offer of safety. She finds both protection and passion in his arms even as an unknown adversary is determined to destroy her information, and her.
Adam and Eve struggle to keep their own secrets in the face of their escalating feelings and the mounting threat on their lives, even when that threat comes from each other.
