Middle Grade Camp Book, third times the charm.
Hello again, everyone. This is the third time I'm asking, but I'm ready to be hurt again. I'm looking for this middle grade book where two best friends, girls, go to camp together. They're used to going to camp at a glamping style camp, but I believe the place got shut down or something, so they have to go to a proper camp instead. They have a falling out at some point, but make up by the end.
The main thing I remember about it is that they have a joke where they get each other to do things by saying, "I'll be your best friend!" The joke being that they're already best friends. And it's reprised at the end when they make up.
I've been searching for this book for ages, and I thought I downloaded it, but I can't find the darn thing anywhere. I'm honestly starting to think it doesn't even exist at this point. I got desperate and searched for it using AI, but came up with nothing even with that.
It's also a standalone, isn't any form of graphic novel, and was probably released after 2010 (not as sure about that).
Last time, somebody said they also remembered this book too, so I might not be crazy after all.
