Four girls from very different backgrounds are making their way to the mysterious Rosenholm Boarding School from different corners of the country. The one thing they have in common is the strange offer they have received to apply for a place at what will turn out to be a school for magic, deeply embedded in Nordic mythology, nature magic, and shamanism. The girls have been invited to apply for a reason that is as yet unknown to themselves, but already during the unorthodox application tests, it becomes apparent that a spirit is trying to establish contact with the girls.

Not to brag, but Brynn Whittaker is basically killing her senior year. She's got the looks, the grades, and a thriving "flirt coach" business that will help pay for her ultimate dream school: Stanford University. But when a highly incriminating video goes viral after the first rager of the year, Brynn finds herself at the center of a school-wide scandal of catastrophic proportions.

The uptight valedictorian lost a bet, and now the whole school’s talking about her kiss with the cocky quarterback... It's just one kiss. That's what everybody at the end-of-summer party says when the bane of my existence wins a challenge and demands a kiss. But it's not just a kiss because everyone knows we've been enemies since kindergarten. So when school starts up, that kiss is all anyone's talking about. Even my crush has taken notice, and I think...maybe he's jealous? And suddenly my enemy's plan to use this rumor to our mutual advantage doesn't seem so crazy, after all.

When Scottie reveals this secret, half the town turns against her, certain that Scottie is lying to protect her sister and that Cait deliberately lost control of the car.
