"It's the start of the school year, and nothing feels right to Justin. He didn't get the teacher he wanted, he's not in the same class as his best friend, and his little sister, Elizabeth, is starting kindergarten at his school. Elizabeth doesn't seem nervous at all. Justin is very nervous about third grade. And to top it off, he's lost his favorite stuffed animal, but he can't tell anyone, because technically he's too old to still have stuffed animals....

The new boy in Nina, Jeff, and Cassidy's class is strange! He's see-through. He floats above his chair. And he never seems to leave the classroom. Could the new boy be a new ghost? Nina and her friends are afraid to find out. And so are the other ghosts! Could this mean more fun for the class in the basement, or more haunting?
