The Popularity Papers #2

It's even harder for best friends Julie and Lydia to navigate middle school when they're suddenly separated by an ocean! Book two in the series that's the basis for the hit streaming show!
 
After spending all of fifth grade studying popularity together, Julie and Lydia are finally ready to put their hard-earned lessons to use in junior high. But before they can, disaster strikes: Lydia’s mom gets a job in London for six whole months! Before Lydia can say “Fancy a cup of tea?” she’s thrust into a new school, where she earns a reputation as “the Violent American.”
 
Meanwhile Julie’s stuck navigating the cliques of American junior high on her own and is adopted by a group of troublemaking eighth graders known as the Bichons. The two best friends will have to learn to keep in touch and stand on their own, assisted as always by their trusty notebook.
