Scary School #3: The Northern Frights

In The Northern Frights, the third book in the spooky Scary School series, Charles “New Kid” Nukid and his friends, including Lattie, a girl ninja, must fight an epic battle with an ice dragon to save their school. But first they must survive going to Scream Academy as exchange students. And that may be hard, because the Academy has an abominable snowman for a principal, a Headless Horseman as one of the teachers, and the students are yetis, trolls, and ogres!
 
Will Charles survive to make an ancient prophecy come to pass and save everyone? The illustrated Scary School trilogy by Derek the Ghost, with its mix of humor, scares, and adventure, is a perfect pick for middle-grade readers of the Wayside School series and the Zach Files books.
