With a new sister on the way, Roosevelt Banks has to give up his bedroom and move into the attic, which must be haunted because of all the squeaks and groans coming from the spooky place at the top of the stairs.

After his plan to move into a fort in the woods fails, and a ghost-busting exercise goes terribly wrong, Roosevelt—with the help of Tommy, Josh, and Eddie Spaghetti—has to find the courage to defeat the biggest, spookiest ghouls ever and turn the Attic of Doom into a Room with a View.
