Obsession (Signet Novel)

After surviving a horrific attack by masked gunmen, Katharine Lawrence awakens in the hospital—with an unfamiliar face staring back at her in the mirror. One thing she does remember is that she’s the special assistant to the head of the CIA—and that she can trust no one. But Katharine’s handsome doctor becomes her newfound protector as she’s drawn into a shadowy world of conspiracy, where nothing is as it seems…and no one is who they appear to be.
