Last summer, Mackenzie and Landon were the perfect couple. And then he dumped her and broke her heart. Fast-forward a year and they’re back at their summer jobs at Serenity Ranch and Spa with Mack and her best friend Bailey, spending their time fantasising about making voodoo dolls and playing childish pranks on Landon.

Luckily for Mack, the perfect opportunity presents itself. Landon takes a nasty fall and suddenly he’s stuck in the past – literally. His most recent memory is of last summer, when they were together, so now he’s calling Mack pet names and hanging all over her.

The plan is simple: keep Landon at arm’s length, manipulate him so he’s the one falling in love, and then, BAM, dump him in the most epic revenge plot in the history of everdom. There’s only one teensy problem: Mack can’t fall for Landon a second time.
