Woke Up Like This by Amy Lea

For two high school seniors, it’s seventeen going on thirty—overnight—in a magical romantic comedy about growing up too fast and living in the moment. Planning the perfect prom is one last “to do” on ultra-organized Charlotte Wu’s high school bucket list. So far, so good, if not for a decorating accident that sends Charlotte crash-landing off a ladder, face-first into her obnoxiously ripped archnemesis J. T. Renner. Worse? When Charlotte wakes up, she finds herself in an unfamiliar bed at thirty years old, with her bearded fiancé, Renner, by her side. Either they’ve lost their minds or they’ve been drop-kicked into adulthood, forever trapped in the thirty-year-old bodies of their future selves. With each other as their only constant, Charlotte and Renner discover all that’s changed in the time they’ve missed. Charlotte also learns there’s more to Renner than irritating-jock charm, and that reaching the next milestone isn’t as important as what happens in between. Navigating a series of adventures and a confounding new normal, Charlotte and Renner will do whatever it takes to find a way back to seventeen. But when—and if—they do, what then?
