The Girl with the Ghost Machine

Book excerpt: When Emmaline Beaumont's father started building the ghost machine, she didn't expect it to bring her mother back from the dead. But by locking himself in the basement to toil away at his hopes, Monsieur Beaumont has become obsessed with the contraption and neglected the living, and Emmaline is tired of feeling forgotten. Nothing good has come from building the ghost machine, and Emmaline decides that the only way to bring her father back will be to make the ghost machine work...or destroy it forever.
