Sweet Little Shamrock - The Shamrock Romances, #2

The world begins to close in around Dewla. Far from her dear home in Ireland, scorned by her mother-in-law and her daughters in a dark and sooty city, Dewla feels more alone than she ever has, and finds it hard to bear up under the petty cruelties of her new family. A bright spot, for her, is when she sits at her husband's sickbed, bringing him back to health, and she and Hugh begin to reconnect, and their love begins to grow at last -- until his mother's scheme, to reunite her son with his old flame, shatters what joy they have, and sends Dewla down a dark path, a path upon which she might not return. Book 2 of the Shamrock Romances by Birdye Latham Hartland.
