Tallulah Tate doesn't believe in elves. She puts them firmly into the same category as unicorns and the tooth fairy. However, when she arrives in Iceland, she hears whispers about little hidden folk who live among the people.

Tallulah has come to Iceland with her father, who is breaking ground on a luxury hotel on the edge of a national park. He has no time for the local legends that threaten to slow his construction schedule.

Tallulah befriends Malen, a local girl who seems sensible apart from her whole-hearted belief in lucky rocks and mischievous elves. Malen is determined to show Tallulah a different side of Iceland - one where nature and magic co-exist.

When a series of strange accidents occur on the construction site, it inflames the fears of locals that the elves are unhappy. Tallulah's father blames the activists that have been protesting his project. Tallulah and Malen have another suspect. All they need is a little proof.

Even though Tallulah doesn't believe in elves . . . they just may believe in her.
