Lying in Shadows — Sofia Grey

Marianne needs to find who's leaking secrets from her company, before they lose another major contract. What she doesn't need is an affair with her married boss. Even worse, to fall in love with him.

She discovers the security leak is more than a case of commercial espionage: someone is lying in the shadows, playing games with them. Now more than her heart and career are at stake--her life is on the line.
