Saving the Last Heir by Lindsey Devin

A dying dragon race.
A stolen heir.
A car heist that could save them.

Jackson Adelmund is the last Alpha of the winged dragons. His species is vanishing, and the only hope left lies in his sister’s egg — now stolen. With time running out, he’s forced into a deadly deal: steal the impossible or watch his bloodline die forever.
She’s not a princess.
She’s a mechanic.

Shyanne Witmer can fix anything—except that now, she’s wrapped up in a mafia mission, driving for her life in a stolen Aventador. Together, they’ll race through city streets, dodge assassins, and risk everything to reclaim what’s lost.

Danger burns. Trust is forged.
And love could be the final theft that saves them both.
