The title says it all; kid goes to camp, makes friends with "cool kids" and gets peer pressured into being a shithead and a bully, wakes up the next day with things reset to arriving at camp.

But the thing is, this book is part of a series. Most of the books are this same kid getting caught up in body swap shenanigans, but he had gotten caught in a time loop once in a previous book. So he knew the score. He just needed to not be a jerk today. Cue him being overly nice to the point of blatant insincerity, making everyone wildly uncomfortable. No growth, just trying to appease the forces that be. Loop continues looping.

Yadda yadda, finally figures out how to be a genuinely nice kid who stands up to bullies and makes friends with the nerdy kid, etc etc, got everything perfectly right.

When that loop doesn't work he immediately throws himself off the bus to camp to kill himself. Loop again.

Finally, having resigned himself to never escaping the loop but at least he can dedicate it to being a good kid with nice friends, a thought occurs to him. There's one thing he hasn't done a single time in all the loops.

He brushes his teeth before bed. And wakes up the next day.
