An epic tale of heroism and passion, of adversity and triumph - The Harrow is a remarkable creation. Visiting their Aunt and Uncle for the summer, Molly and Elizabeth venture under a sycamore tree and find themselves in a fantastical world known as the Harrow. The girls know little of the troubles that will soon plague this new world but are guided by their Uncle's pet cat to a meeting of wizards. Here, they meet many other friends of their Uncle and learn that a long dead evil has been reawakened and is plotting to destroy the world. The sole weapon against this darkness rests on a necklace given to Molly by her Uncle, the Lia Fail stone, which could only be used by the Queen of Ahlgren. The stone's magical powers begin to empower Molly as Queen, upon whom all hope rests. Soon storms from the east bring the Uakor Turg, dreaded minions of evil, while ghost demons and dark wizards wage war across the lands and capture the sacred tree of peace, the Aina Dur. To save the Harrow, Molly and her sister must begin an adventure with others to face the darkest of evil.
