This joyful celebration of fandoms, theme parks, whirlwind romance, and plus-size girls follows eighteen-year-old Lia, who's determined to win an epic scavenger hunt at a world-renowned theme park—until rival contestant Mason upends her plans and sends her heart careening off the tracks.

Most high-school seniors look forward to graduation and everything that comes after, but Lia Baker just wishes time would stand still. In a few months, while her best friends will be heading off to college, Lia will be stuck at home, buried under the pressure of a full-time job and her mother’s anxiety—or so she thinks, until a once-in-a-lifetime opportunity is suddenly within reach.

When Lia lands a highly coveted spot in an exclusive 50th-anniversary scavenger hunt at Fableland, she seizes the chance to finally have an adventure of her own. But it's much more than just a vacation to Lia; the contest winner will receive a cash prize, one that Lia plans to use to move out of her parents' house, get a job at Fableland, and eventually pitch her story about a plus-size princess. It's a golden ticket into her dream world—and a way to help create that dream for others.

With her extensive Fableland knowledge at her fingertips, there’s no way she won’t win. Especially once she meets Mason—a cute rival contestant who wants to team up to decipher the scavenger hunt’s daily clues. But as her time at Fableland ticks away too quickly, Lia realizes that she will have to choose between the future she wants to rewrite—and a love she hadn’t planned for.
