Hound Dog True by Linda Urban

Custodial Wisdom: Never use a metal ladder in an electrical storm.  Bring an extra garbage can to the cafeteria on Turkey Drummettes day.  Fix things before they get too big for fixing.  Mattie Breen has always been the new girl.  She doesn’t know if she can bring herself to make new friends this year, so she convinces her Uncle Potluck to take her on as a custodial apprentice.  That way, she can work with him at lunch and recess instead of having to be with all of the other fifth-graders.  What she doesn’t plan on is Quincy Sweet popping up all of the time and Uncle Potluck’s bad luck.
