The four of them were thick as thieves long before an unfortunate lab accident sent them careening into the afterlife. So when they hear about a machine that could return them to the land of the living, they are determined to steal it.

Because pulling off the score of their deathtimes is no job for an amateur"--,Front jacket flap.
