After dying, high school senior Charlotte Usher is as invisible to nearly everyone as she always felt, but despite what she learns in a sort of alternative high school for dead teens, she clings to life while seeking a way to go to the Fall Ball with the boy of her dreams.

When Petula becomes deathly ill, her sister Scarlet seeks help from former classmate Charlotte, for whom the afterlife has become burdensome, leaving her just as insecure and isolated as she was while she was alive.

Three modern-day teens have been reincarnated as saints-or so they've been told. They watched as Sebastian sacrificed himself for what he believed in, and now they have choices to make of their own. Will the girls trust in their destinies as saints and martyrs and perform the miracles as Sebastian instructed? Or will they lose faith in themselves and each other in his absence? Time is running out for them to make a decision, and the fate of the world...

Charlotte has been given her first assignment after graduating from Dead Ed- the alternative high school for dead teens- she is to go back and help out a student from her previous life and her first love, Damen.
