The Seeds of Heimdall. The Four Masters Series

As the last decade of the first millennium approaches, the struggle for power in Ireland is intensifying. The High King, Mael Sechnaill Mór, seeks to dominate and is bent on conflict. One provincial king in particular stands in his way. In Munster, Brian Ború conceives an audacious plan to throw off the influence of the north, but treason stalks the halls of Ceann Coradh. The hidden hand of politics has thrown fortunes and futures into turmoil in Rannal Halvorsen's family, setting brother against brother.
As they are drawn once more into the eye of the storm, fighting for their homeland, lessons must be learned, or all could be lost before they can confront the ultimate test of strength. Viking warlords play to their own agendas, striving to maintain independence from the old order while vying for power among themselves. In this, the concluding part of the Four Masters Trilogy, the escalating tensions brought by tribal, class, religious and cultural divisions bring a foretaste of the spiralling conflict between two giants of Irish history whose stories will dominate the next quarter of a century and echo down to today.
