Sunscreen alert! Jessica and the Unicorns are headed for the balmy, boy-filled beaches of Hawaii!

From the personal journal of soon-to-be eighth grader Jessica Wakefield:

Okay, you do the math: friends + summer - parents + Hawaii. What does that equal? Aloha? The answer should be obvious.

But it isn't. This Hawaiian vacation is kind of... freaky. And I'm not even sure why. All I know is that my friends aren't who I thought they were... not anymore. Have they changed? Or have I?
