When Emmaline Beaumont's father starts building a ghost machine, she doesn't really believe it will bring her mother back from the dead. But Monsieur Beaumont is so desperate that he's done nothing but toil away on the contraption year after year.
Nothing good has come from the hours Emmaline's father has spent in their basement, working on the ghost machine. Feeling utterly forgotten by the only parent she has left, Emmaline decides that she must take action. The only way to bring her father back will be to finally make the ghost machine work . . . or destroy it forever.
