Dying is always bad, and dying young is even worse. For Casper Moore, though, losing his life to an illness was only the beginning. Saddened by his demise, a benevolent (?) Goddess sent Casper's soul to a world of magic and RPG-like rules. There's just one problem—she forgot to give him a new body! Stuck as a harmless—well, almost—Ghostling, he must find a "vessel" to "possess" if he wants to survive another day. For the time being, a squirrel will do it.  In the world where his mere existence is a sin, Casper will make a place for himself with his ability to possess living beings and corpses alike. He's going to make some friends and even more enemies, but only if he manages to figure out how to stop being a cute little squirrel first and raises his Level. Follow his journey as he fights off a secret society of evil shifters and hides from zealous crusaders of the Church, all the while trying to remain human when he's literally anything but.
