Mischief by Stefania Shaffer

Getting Away with Mischief

Fifth grader Slater Hannigan wants to keep his big man on campus status. It does not matter that he glued his teacher’s chair cushion to her skirt last year—he gets away with everything because of his powerful mother who has secured his popularity by throwing him over-the-top Halloween Haunts.

But when the friendless girl in class discovers the secret that will finally mean real trouble for Slater if he gets caught—and embarrass his father the D.A.—this one will be too big for her to keep.

MISCHIEF appears as the first in a 4-book series for Middle-Grade readers.

She is competing against all of those other books you read and is hoping to get your friends interested in reading all about Slater, Macaroni, and, of course, me.

It’s pretty easy. Just go to and then type in Stefania Shaffer.

Yours truly,
Sibley White
