Maybelle works as a mechanic fixing bots and ships on Rove City and she loves it. Her life should be good. Except that her merchant father hasn't returned from his most recent trip, her younger sisters need more than she can give them, and the family is quickly running out of money. Not to mention, Gabor, a local security guard, has decided he deserves Maybelle's affections—at any cost.

She's managing, until Gabor takes his attentions one step too far: he threatens her sisters. Maybelle realizes that she can't protect them alone—it's time to track her father down. But when she finally finds him, she discovers that it's not that simple. He's being held prisoner by Amarok, a temperamental cyborg who will only let her father go under one condition: Maybelle stays behind in his place.

For the sake of her sisters, she agrees, but soon discovers that there is far more to Amarok than meets the eye. The longer she stays on board his ship, the clearer it is that something strange is going on—but she doesn't know what it is or how to fix it.

The Silver Arm is a science fiction retelling of Beauty and the Beast, and the third in the Rove City series.
