Marlowe Jenkins and Priscilla Covington-French hate each other. Always have, and in Marlowe’s mind, always will, even though they haven’t been in the same room in almost twenty years. There’s no denying the rivalry between the two women, or maybe – just maybe – the constant tension between them is because they kissed. More than once. Impossible to say.

But for the first time, well, ever, Marlowe and Priscilla must work together when they learn that their high school drama teacher sent himself through a time machine hidden within the school’s walls. Despite their decades-long feud, they somehow keep coming across alternate versions of themselves who are also dealing with very strong feelings toward each other…

As the only constants in their ever-shifting realities, Marlowe and Priscilla begin to trust and rely on each other. The more time they spend together, the more both women realize they squandered their potential happiness back in high school to protect their pride and egos. Now they must make a choice that’ll change their reality forever: either play it safe and stick with their all-consuming feud, or take a leap and bet on each other.
