Darkness of Day.

Draven Noir is a vampire with a gift. One day out of the year he gets to walk in the sunlight. The only catch is that to do it again the next year he must save the life of a vision he sees before the next day. If he fails then he is doomed to the darkness forever. This year he must use his fast gun and quick tongue to figure out how to save the life of someone who is already dead.
