In the shadow of the nation's capital, Kate Livingston's respectable life as a government worker is disrupted by an encounter with the insufferable Trevor McDonough, the one man she'd hoped never to see again. A Harvard-trained physician, Trevor never showed the tiniest flicker of interest in Kate, and business is the only reason he has sought her out now. Despite her misgivings, Kate agrees to Trevor's risky proposal to join him in his work to find a cure for tuberculosis. As Kate begins to unlock the mysteries of Trevor's past, his hidden depths fascinate her. However, a shadowy enemy lies in wait, and Trevor's closely guarded secrets are darker than she ever suspected. As revelations from the past threaten to destroy their careers, their dreams, and even their lives, Trevor and Kate find themselves in a painfully impossible situation. With everything to lose, they must find the strength to trust that hope and love can prevail over all.
