"Ghost Diet" starts off this fun ten-story collection of Marble Grant stories with the question: What can a ghost eat? Answer: Anything she wants if she exercises to keep her weight down. Especially since food tastes better as a ghost. Marble Grant and Sims, her lover and partner live in beautiful high-rise condo and spend their days in people's minds trying to find what they can do to help. Both work as Ghost Agents in the Poker Boy Universe.
And sometimes they run across really, really bad people they must stop. What they do to those really, really bad people makes you wish Ghost Agents existed in this "real" world. Ten great Marble Grant short stories. Tons of fun, tons of partying, and two beautiful ghost drinking. And doing really fun stuff to really, really bad people.
