Ireland, even ore the most of Europe, trembles for the Norse raids, especially in treasure repositories like the rich Benedictine monasteries. Young Brendan is entered by his uncle, abbot Cellach, into Kells monastery. The abbot is obsessed with fortification in case of a Viking attack, the boy with is opportunity in the abbey's scriptorium to help famous illustrator Aisling finish the famous book saved from the Viking raid in the monastery isle of Iona. That mean dodging wall building duty and venturing into the dark, dangerous, forbidden forest in search of rare color ink ingredients.
