When Lavender Blue learns that the Banshee, the faerie messenger of death, will soon visit her best friend Rose, she makes a desperate wish on a star. Her prayer for a chance to save Rose is granted by the faeries of Galtee Wood, and Lavender finds herself entangled in an ancient and magical quest that will lead her through the perilous faerie realm.
As Lavender races to reach her best friend before the Banshee, she finds herself facing more and more dangers than she could have imagined, dangers that will test her wits, her courage and her love to the limit.
Can Lavender find the strength to overcome the magical dangers and dark faeries in time to save Rose? Or as the blackness of night veils the woods, will the piercing cry of the Banshee warn that she is too late?
