Sixteen-year-old Millie Novak is stuck in an "if only" rut. If only she were stronger and faster, maybe her roller derby teammates would take her seriously. If only she had the guts to go back to in-person learning, maybe she'd have a social life. If only she weren't such an awkward mess, maybe she could get the attention of that cute girl on the all-star derby team. And don't get her started on her family!
After the one-two punch of her beloved older brother's departure for college and her parents' overdue split, Millie decides it's time to reinvent herself. With the help of her new friend Pumpkin and a little bit of deceit, Millie crafts a plan to cement her status on the team and get her crush to fall for her.
But reinvention isn't easy. Millie's constantly shown up by show-off teammate Stork, and the only way she can get her crush's attention is through increasingly elaborate lies. Worse, she begins to suspect Pumpkin is not the supportive friend she'd imagined. Toughest to handle? Realizing the person she's in love with might not be her longtime crush, after all.
