Ashes to Weddings & Other Marble Grant Stories — Dean Wesley Smith

The story "Ashes to Weddings" jumps you right into this fun ten-story collection of Marble Grant stories. Marble Grant and her ghost partner and lover Sims fight crime by crawling around inside of people's minds. Yeah, kinda creepy but they got used to it.

And they save a lot of people's lives. Stop bad people, help good people. A great job. Better than walking into the light to the next world. Here they still party, drink, and make love. And as a ghost, everything feels more intense. Way more intense. 

Ten fun Marble Grant short stories with two ghosts saving lives all day and partying all night. A great life if you didn't have to die to get the job.
