She's the spark he's been missing. Sebastian Pierce leads a predictable life as the chair of a college math department. When he inherits a rusty mess of a car from his estranged uncle, along with some unusual stipulations, there's only one woman who can help him-and getting off on the wrong foot might cost him everything. Margot Ripley took over her father's struggling garage, turning it into a hub of female mechanics as the Saucy Wrench. She's busy digging the business out of the debt he left it in, and restoring a classic car for a stuffy, boring professor doesn't fit into her schedule. Still, she can't resist the opportunity to finally follow her passion instead of sticking to the usual grind. As the restoration unearths even more mysteries, Margot and Sebastian become the focus of something ominous, and they'll have to rely on each other to untangle the threads that threaten to entrap them both. Passion unites them, but a web of danger might tear them apart.
