Allie's excited about her class field trip. She gets to ride on a bus, which she never gets to do, living so close to school that she actually has to walk there every day!

But then Mrs. Hunter announces that every student in Room 209 has been assigned a "buddy" for the day--from Allie's old 4th grade class at Pine Heights Elementary--and her buddy just happens to be her ex-best friend Mary Kay, who betrayed Allie right before she moved! This is one field trip Allie's definitely going to need to need to write some major rules for.

Allie's excited about her class field trip. Sure, it's to a historic one-room schoolhouse, built back before there was the Internet or even cell phones, and Allie's teacher is encouraging everyone to dress up in old timey costumes, which some of Allie's friends are actually doing.

But then Mrs. Hunter announces that every student in Room 209 has been assigned a "buddy" for the day--from Allie's old 4th grade class at Pine Heights Elementary--and her buddy just happens to be her ex-best friend Mary Kay, who betrayed Allie right before she moved! Allie is going to have to spend a whole day sharing an old-timey desk with a big crybaby!

As if things aren't bad enough, with renovations going on at Allie's house--there's a hole in the wall that her kitten, Mewsie, keeps disappearing into. What if Allie's mom and dad and Uncle Jay make a mistake, and Mewsie gets trapped inside the wall forever?--and with Cheyenne O'Malley and Brittany Hauser getting assigned to be "buddies" together, it looks like this is one field trip Allie's definitely going to need to need to write some major rules for.
