School is over. But the adventure has just begun. . . .Eighteen-year-old Cass Issac doesn’t believe in sticking around. She's had to move a lot due to her dads' house-flipping business—always a different school, always a new friend group. She’s learned there’s no need for drawn-out-goodbyes with people you'll lose touch with anyway. Which makes Grad Nite at Disneyland the perfect way to finish up high school, and have a magical last night with her best friend, Bryony – before she leaves once again.But amid the roller coaster rides and Cars Land dance party, the night turns into one big disaster. When she meets cute British bassist Freddie Patel, she accidentally ruins his big break. Worse still? Cass gets in a major fight with Bryony. And instead of being able to make a quick exit, she’s thrown for a literal time loop. Which means the queen of ghosting has nowhere to go as she’s forced to relive the most dramatic night of her life, over and over. Now, Cass will have to find a way to make things right . . . or be stuck at Grad Nite forever.
