Esme and Kayla once were campers at Camp Pine Lake. They're excited to be back this year as CITs (counselors in training). Esme loves the little girls in her cabin and thinks it's funny how scared they are of everything—spiders, the surly head counselor, the dark, boys . . . even swimming in the lake! It reminds her a little of how she and Kayla used to be, once. Before . . . it happened. Because Esme and Kayla did something bad when they were campers. Afterwards, the girls agreed to keep it secret. They've moved on—or so they say—and this summer is going to be great. Two months of sun, s'mores, and flirting with the cute boy counselors. But then they get a note. THE LAKE NEVER FORGETS. And the secret they've kept buried for so many years is about to resurface.
