The Fox and the Rebound by Mary Frame

She made a deal with the devil and he’s determined to collect. But when passionate sparks fly, all bets are off.

Piper Fox hates clocks. With her confidence shattered by a bad break-up, the creative welder can’t stand another minute of her debilitating artist’s block. So with time running out on her deadline, she tests a wild theory that the best way to get over a jerk is to get it on rebound-style with crazy-rich and broodingly handsome Oliver Nichols.
Oliver Nichols curates a cool facade. So when sparks fly with the stunning artist he has under contract, the eccentric billionaire does his best to stifle his reactions. And though he’s convinced love isn’t in the cards for him, ever, the lonely philanthropist can’t stay away.
Not sure how to make the next move after chickening out once before, Piper struggles to ignore her stalkery ex and keep her nose to the grindstone. While Oliver fools himself that keeping a close eye on the vulnerable metalworker is just a matter of good business, only to discover she’s somehow snared his heart.

Will the thrill of danger push them into a forever embrace?
