Blast from the Past

Blast from the Past is the sixth novel in Allie Finkle's Rules for Girls by Meg Cabot and published by Scholastic in 2010.

Description
"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. GAH! But at least 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 Walnut Knolls Elementary School, with whom Pine Heights Elementary is pairing up for the trip. And Allie's 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! Not to mention keeping Joey Fields—whom everyone on the bus keeps calling her boyfriend—from being beaten up by the boy who used to call her Stinkle Finkle, Scott Stamphley.

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 blast from the past Allie may not survive. In fact, she's had enough with old-timey things. It might be time to employ some new rules!"
