<div>Miss Mackle is getting married! But she didn’t invite any of her students to the wedding. The kids don’t understand it: a wedding is a time for families to be together, and they are Miss Mackle’s Room 3B familywhich is especially important because her father is in the military overseas, and he won’t be home for the wedding. So Harry comes up with a plan to sneak his pals into the wedding ceremony and hide in the back. It seems like the kids are going to make a horrible mess of their teacher’s wedding . . . until they find a way to save the day for all involved.</div>
