A wicked adventure-or deadly...trollble

For sixteen-year-old harpist prodigy Moira, the annual Dairy Princess event in Vanderby is just another lame publicity "op." Moira a dairy princess? Get real. Twelve girls have been selected to have their likeness carved in butter and displayed on the Trollholm Bridge. It's a Vanderby State Fair tradition that has been going on for, like, ever.

As far as Moira is concerned, the sooner it's over with the butter-er-better.
About the same time and not far away, three brothers-members of the sensationally popular teen boy band The Griffsons-are in the middle of a much needed road trip to relax from the pressures of their latest tour.

In a flash, however, the kids are suddenly transported to a strange and mystical wilderness where they find themselves in the middle of a deadly tug-of-war struggle between a magical fox named Fossegrim and the monstrous troll Aenmarr of Austraegir. At the heart of the feud is a battle for possession of a mysterious magical fiddle—and an ancient compact between Trollholm and the outer world.

Whatever. All Moira cares about is that eleven of her fellow princesses have been enchanted into a slumber and Moira needs to figure out a way to awaken them...and get home.

Unfortunately for Moira and the Griffsons, nothing in Trollholm is as it seems. Finding a way out of Trollholm may be a lot more difficult than they think.
