Eithne Massey has written many books for both adults and children, mainly based on the legends of Ireland. Her adaptation of the award-winning movie The Secret of Kells is set in the time of the early Viking raids; The Silver Stag of Bunratty and Where the Stones Sing are set in Norman Ireland and Blood Brother, Swan Sister at the time of the Battle of Clontarf. All blend together historical detail with myths, legends and folklore, resulting in stories which will appeal to "young readers who enjoy an adventure with well-rounded characters and a touch of magic and history" ( www.childrensbooksireland.ie).
