From the author of the award-winning This Journal Belongs to Ratchet comes a new kind of journal by a girl on a madcap road trip, featuring a karaoke-loving grandma, a cute boy, and a wild summer of memories that will last a lifetime.

Samantha is not exactly excited to spend what was supposed to be an awesome summer vacation with her grandma all the way in Florida. Or to be testing out her mom's "Dear Me" Journals—writing to her future self just feels weird. But it turns out Gram has some not-so-boring plans up her sleeve…

Gram and her friend Mimi are going to audition for the Seniors Have Got Talent Karaoke Contest!

A road trip in Gram's new Mustang turns into a series of hilarious mishaps that flip Samantha's summer on its head. And to make things more awkward, Brandon, Mimi's totally handsome grandson, is also along for the ride.

It looks like those journals just might be worth keeping after all. Because this summer will be one Samantha will never want to forget.
