I'm partial to this book because I wrote my master's thesis on it. So I'm giving it four stars because I find it so interesting, rather than for the quality of its prose.
Emily Lawless was a peer of W.B. Yeats, Lady Gregory and the literary nationalist movement (otherwise known as the Celtic Twilight)--respected authors of their time who were trying to create an Irish national identity through very idealized portraits of Irish Catholics/the peasantry.
Hurrish, written against the backdrop of the Irish Land Wars of the 1880s, gives a much more problematic view of Ireland at that time. Lawless, as a member of the disenfranchised Anglo-Irish landlord class, asks important questions about what Ireland is becoming.
