The Lost Angel

Michael is an archangel looking for his fellow angel, Gabriel, who disappeared while on the hunt for Samuel, more commonly known as Lucifer. He is sent to a small town where Gabriel was last heard from. There, he finds a human girl, by the name of Gabrielle, who seems to know why he is there and who he is looking for. She doesn't remember anything else other than Samuel, Gabriel, and a bright light. Every piece of evidence points to the fact that Gabriel is dead but he cannot shake the feeling that he is still alive. After all, who is this girl who seems to know everything he came to do and why does she wear Gabriel's necklace?
