A group of girls has attended Camp Sunnyside every summer for years, and although they don’t live in the same towns and don’t usually see each other outside of camp, they’ve formed a strong bond from their shared summer adventures.  Most of the books take place at the camp and focus on the girls’ friendship, adventures, lessons learned, and relationships with their camp counselors and other campers.  Sometimes, there are boy characters from Eagle, a boys’ camp across the lake from the girls’ camp, who are allowed to visit for special occasions and for special projects.

The stories focus on the girls of Cabin 6 at camp:

Katie Dillon

She is often the leader of the other girls.  She has a lot of good ideas, although occasionally, she can be a bit bossy and pushes others into doing things they don’t really want to do.

Trina Sandburg

Trina is a little shy and sensitive.  She isn’t fond of competitions because she doesn’t like to see anyone lose and doesn’t like to take part in public performances, with everyone looking at her.  However, she’s a good gymnast and doesn’t mind when people watch her do gymnastics.  She’s also good at organizing things.  Trina’s parents are divorced.  Eventually, her mother marries Sarah’s father, and the two girls become step-sisters.


Megan is an imaginative daydreamer.  She loves tennis and is good at it.

Sarah Fine

Sarah prefers reading to sports.  She likes good food and can eat a lot, but sometimes, she worries about her weight and diets.  Sarah’s mother is dead, and she lives with her father.  Eventually, her father marries Trina’s mother, and the two girls become step-sisters.


Of all the girls, Erin is the one who most tries to act grown up.  She likes to experiment with makeup, and she’s interested in boys.  She sometimes feels like the other girls should start acting more sophisticated and mature.

Different books in the series focus on different girls, giving them the main point of view.  The counselor of Cabin 6 is Carolyn, and the girls are fond of her.

Official Camp Sunnyside Song:

“I’m a Sunnyside girl, with a Sunnyside smile,
And I spend my summers in Sunnyside style,
I have sunny, sunny times with my Sunnyside friends,
And I know I’ll be sad when the summer ends,
But I’ll always remember with joy and pride,
My sunny, sunny days at Sunnyside!”

Even the girls in the story sometimes think of their camp song as being a little corny, but they have a lot of nostalgic memories associated with it. (In a way, I feel similarly about the books themselves.)
