Thirteen-year-old Jenna is excited to have all of her friends visit her lake house for the Memorial Day holiday and local fair until she finds out her twin brother has invited David, her friend's boyfriend who she had a crush on.

The girls from Camp Lakeview keep in touch through a blog as Priya deals with a science fair project, Alyssa fights for the chance to be featured in an arts magazine, Val vies for a spot in a dance recital, and a Tori attracts the attention of the son of one of her father's clients.

Separated from her friends by different bunkhouses and activities, Sarah's second summer at Camp Lakeview gets even worse when an injury and an attentive boy interfere with her reputation as the camp's star athlete.
