What began as an innocuous advice column for Celeste Cleary has transformed into an all-consuming obsession, and her former existence as a scientist now feels like a distant memory. As she immerses herself in the troubles of others-at times solving their dilemmas with messages from beyond the grave-an ability that has invaded her life since the hit-and-run accident that nearly killed her months before, Celeste grapples with the news that the accident may have been attempted murder.

A terrible hit and run accident took Celeste Cleary's life until doctors managed to bring her back. But now she's... different. Once a respected scientist, she walks the thin veil between the living and the dead. As she struggles to return to her former life, Celeste receives an email-a heart-wrenching letter from a stranger, a woman begging for help locating her seventeen-year-old sister, Katie, who vanished a year before.
