Snapper Rodriguez never met a woman or a racer he didn’t like, until Gina Morales shows up. She’s butting her head under every hood, moving his tools and plain annoying. He’d rather fall down a mine shaft and lose his other limb than put up with her any longer.

Gina Morales is still trying to figure out what it means to be human, and as the first AI with a body in existence, she’s eager to find her maker. A racing garage like Full Throttle seems like a great place to start, though the head mechanic is an ass and she can’t help but get involved when their latest racing engine fails.

When Snapper and Gina are forced to work together to create a new engine and steal parts from competing racing gangs, the thrill of the job and the close quarters bring unwanted attraction. Too bad Snapper still wants her gone and will do anything to make that happen, even promise her tastes of human connection that she’s never experienced before. As things heat up, the threat to Gina’s synthetic heart grows, along with her confusion. They’ll have to decide if love is worth the risk or if this is a finish line they can’t cross.
