Book excerpt: Are angels real? Simon Cross, professor of the occult, scoffs at the idea but accepts the challenge when he's invited to London to study an artifact purported to be the key to understanding Enochian—the language of angels. Elizabeth and Charlotte join him for the Christmas holiday and find themselves left to their own devices. With the help of a mysterious stranger, who Elizabeth suspects just might be an angel himself, they set out to create the perfect holiday for a group of lonely seniors. When Simon's work becomes an obsession, it takes a little Christmas magic to remind him of the power of love and the true meaning of Christmas.
