Having surrendered her happiness to raise her children, Eva Fitzgerald defies convention in 1950's Ireland by leaving a failed marriage to embark on an extraordinary journey of self-discovery. It takes her from teeming Moroccan streets and being flour-bombed in radical marches in London to living in old age in a caravan that becomes an ark for all those whom she befriends amid the fields of Mayo. An indefatigable idealist, Eva strives to forge her identity while entangled in the fault-lines of her children’s unravelling lives. An Ark of Light is a devastating portrayal of a mother’s anxiety for her gay son in a world where homosexuality is illegal and explores a terse relationship between a mother and daughter with nothing in common beyond love. Remarkably affecting and gorgeously rendered, this standalone novel completes the real-life story of the unforgettable heroine of Bolger’s bestselling novel, The Family on Paradise Pier.
