Monsters on the March by Derek the Ghost

If you read Scary School and liked it, I would recommend Monsters on the March.  It is about an eleven year old ghost writer, who goes on a field trip with the whole school to see the Monster King.  Then Charles Nukid rescues Princess Zogette.  He must marry her because he saved her. Then they get attacked.

I liked it because it has adventureand very silly parts. Like when they make a human chain.  That is why I liked it.
