Fresh from university, Eliza Hardison is determined to crusade for workers’ rights until her cousin Dexter, the Makesmith Baron, prevails on her to represent Hardison House in the American Dominion Sky and Steam Rally.
 
The competition is fierce, but only one opponent really matters to Eliza. Dexter’s protégé, Matthew Pence, was always like a big brother to her. But now she’s grown up, and Matthew has made a break from Hardison House with his own business venture—and made his own entry in the rally.
 
Matthew intends to win while keeping Eliza safe on the perilous route from New York to San Francisco. As the threats escalate through treachero's skies and uncharted American wilds, though, Eliza and Matthew must work together, discovering a bond deeper than either could have imagined…but is winning the rally more important than winning at love?
