Elite guest list. Vera Wang gown with matching Jimmy Choos. Charming tuxedo-clad boyfriend. Velvet rope.

Teagan Phillips's sweet sixteen is the event of the season. Other parties have been chill, sure, but no one at Rosewood Prep throws a bash as extravagant, exclusive, or over-the-top expensive as Teagan. No one is as obnoxious, either. But that doesn't stop everyone from wanting to see and be seen at her birthday.

Luckily, Teagan's in for a rude (and rather ungraceful) awakening. On the big night she falls stilettos-over-tiara into the country club wine cellar and blacks out. When she comes to, there is a strange woman standing at the foot of the stairs.

Teagan initially mistakes this mystery woman as one of the help, but the stranger's true purpose is to take Teagan on a ride, bringing her back through time to show her some very unpretty realities. At the end of it all, if she's lucky, Teagan and her visitor just might put the sweet back in sixteen...
