So he can't really focus on his grandpa's death. Besides, how do you grieve for someone you barely knew? But then Michael starts seeing his grandpa's face in the mirror--and he seems to be reaching out for help. Soon, Michael is slipping out of his body and into his grandpa's memories--wading in the river between the living and the dead. As the slips become longer and more frequent, Michael struggles to resolve the feud that ripped his family apart. But each time he visits the world of the dead, it becomes harder to return. He will have to rely on an unlikely group of friends to keep from slipping forever. . . .
