The Red and the Green by Iris Murdoch
As the Easter Rebellion looms, tension mounts in the rain-soaked streets of Dublin. Tension is also ratcheting up at home. Pat Dumay is a Catholic and an Irish patriot. His relentlessly pious mother pursues her own private war with his stepfather, a man sunk in religious speculation and drink. Meanwhile Pat's Protestant soldier cousin, Andrew Chase-White, puzzles out his complex emotions about Ireland and the girl he loves. Weaving between them moves Millie Kinnard: fast, feminist, and only just respectable.
