The ghost in love

A man falls in the snow, hits his head on a curb, and dies. But something strange occurs: the man doesn't die, and the ghost that's been sent to take his soul to the afterlife is flabbergasted. Going immediately to its boss, the ghost asks, what should I do now? The boss says, we don't know how this happened but we're working on it. We want you to stay with this man to help us figure out what's going on. The ghost agrees unhappily; it is a ghost, not a nursemaid. But a funny thing happens--the ghost falls madly in love with the man's girlfriend, and things naturally get complicated. Soon afterward, the man discovers he did not die when he was "supposed" to because for the first time in their history, human beings have decided to take their fates back from the gods. It's a wonderful change, but one that comes at a price.--From publisher description.
