Tanya has a secret. She can see fairies.

But not the fairies we imagine. These fairies cast spells on her, rousing her from her sleep and propelling her out of bed. Disturbed by her daughter’s behaviour, Tanya’s mother sends her away to live with her grandmother at Elvesden Manor, a secluded countryside mansion on the outskirts of town.

Then an old photograph leads Tanya to an unsolved mystery. Fifty years ago a girl vanished in the woods, a girl Tanya’s grandmother will not speak of. Tanya is determined to find the truth, but as she unearths more secrets she finds herself dangerously close to following in the missing girl’s footsteps . . .
