His business failing and his marriage floundering, Harrison Holden is falling apart. To make things worse, he wakes one morning to see Piers Claybrook, a man he rescued after a car crash, standing in front of him—the same Piers who'd died in the hospital the night before. Now a ghost, Piers believes he's with Harrison to make a difference in the other man's life. It's up to the two of them to find the key to living—and dying—and how to walk the line in between without being separated by it.
