Molly Perkins is an elderly lady who tells the story of her experience of having a guardian angel by the name of Sebastian enter her life at the age of fourteen. Book one of the saga primarily deals with her early experiences. Sebastian tells Molly that God has chosen her for a special reason, which she will learn about more as she grows older. For now, she must learn what Sebastian has in store for her in her daily life as he provides help for her through one difficult situation after another-which is not easy in a primarily Godless world.
