Months ago, arsonists burned Dr. Damon Sinclair's laboratory. Now Damon is a recluse, shut in at the top of his unfinished Sinclair Tower. And at the very bottom is the affectionate Kit Snow and her down-home diner.

After stopping a back-alley mugging, Kit earns the gratitude of the dark knight doctor. Only, she doesn't want his charity-just all of his most intimate secrets-putting her between her mysterious protector and the black marketers seeking to pillage the Sinclair pharmaceutical empire. But the only thing Damon guards more closely than his multimillion-dollar formulas is his heart.
