Our story begins with timid, animal-loving, 11-year-old named Laura Griffin who lives with her family in the west of Ireland.
When her pet lamb becomes gravely ill, she unwittingly calls for the help of a powerful Sidhe Goddess from an ancient realm.
However, the youngest member of this mythical tribe decides to tag along too, and a magical friendship begins.
But the Sidhe are in danger! The Féth Fíada – a violet mist that protects and sustains them, is fading. It can only be made when the sun and the full moon shine into the mound of Knowth at the same time on the equinox.
Strangely, one of the passages is blocked. With only hours until the full moon rises, Laura embarks on a perilous journey to save the Sidhe realm and her best friend, before they disappear forever.
Laura soon discovers that there are darker forces at play – deadlier than she could ever have imagined…
