"For the girl called Gilly, life in the wilds of Birnam Wood is little more than a desperate struggle for survival. Seven long years have passed since she was first taken in and sheltered by Nettle and Mad Helga, the hut-dwelling wise-women whose inscrutable powers of alchemy and prophecy are feared and reviled throughout good King Duncan's kingdom.

Living under the threat of deadly persecution by witch-hunting villagers, the threesome ekes out a life by peddling potions and elixirs, scavenging for food, and robbing the bloodied corpses of Scotland's battle-scarred hills for precious metals and weapons." "But Gilly is haunted by recollections of a much brighter life. She clings to fading memories of a time when she was contented and adored - until tragedy swept all that happiness away and young Gilly's life was changed forever.".

"Obsessed with avenging her loss and putting out the fire that still rages in her heart, Gilly has dedicated herself to destroying Macbeth, the boundlessly ambitious man who took away her childhood, and his goading wife. Disguising herself as a poor servant boy, she insinuates herself into their lives and, as she bears horrified witness to Macbeth's violent path to power, Gilly subtly begins to take a hand in the forces governing his fate.

But as the culmination of her revenge draws near, Gilly finds her own life at risk when she confronts the troubling legacy of a long-concealed heritage."--BOOK JACKET.
