After their parents' shocking revelation about their fae heritage and an attack on their lives, the McDonald twins are forced to hide out deep in the Swiss Alps at Riverdale Academy, a secret vampire slayer training facility. And with no way to contact their vampire boyfriends for rescue, they're going to have to play nice with the locals. But when Sunny starts acting strange, Rayne realizes that there's more to fear at Riverdale than getting staked by the student body--leading to a showdown in Fairyland that may cost the twins their lives.
