September Surprises

September Surprises is the sixth book in the Main Street series.

Summary
It's September in Camden Falls, and it's time for Flora, Nikki, and Olivia to move up to the Central School from their old elementary school. As seventh graders, they'll be sharing the halls with kids from other towns - and from grades as high as twelfth. Flora and Nikki are excited...but Olivia isn't at all. She's always been the youngest in her class. Now she's the youngest girl in the whole school - and plenty of kids, both friends and bullies, are noticing. When Olivia runs afoul of a popular girl, she realizes she has to grow up fast...or get left behind.
