Everyone is (still) afraid of something...

Madeleine Masterson is deathly afraid of bugs, especially spiders;

Theodore Bartholomew is petrified of dying;

Lulu Punchalower is terrified of confined spaces;

Garrison Feldman is frightened by deep water. . .

After discovering that each of her former students has secretly regressed, headmaster Mrs. Wellington brings Madeleine, Theo, Lulu, and Garrison back for mandatory summer school. Facing their fears is terrifying enough, but when they are joined by a fifth student (and another mysterious entity lurking in the woods) things start to get even scarier.
