When a prom-decorating snafu sends her crashing into her archnemesis J. T. Renner, Charlotte Wu wakes up in an unfamiliar bed at 30 years old next to her fiancé-J. T., and together they must find their way back to 17, making some surprising discoveries about each other along the way.

Planning the perfect prom is one last "to do" on ultra-organized Charlotte Wu's high school bucket list. Then a decorating accident sends Charlotte crash-landing off a ladder, face-first into her obnoxious archnemesis J. T. Renner. Worse, she wakes up in an unfamiliar bed-- thirty years old, with her bearded fiancé, Renner, by her side. Somehow they have been drop-kicked into adulthood, trapped in the thirty-year-old bodies of their future selves. With each other as their only constant, Charlotte and Renner discover all that has changed in the time they have missed. Reaching the next milestone may not be as important as what happens in between. -- adapted from jacket
