<P0-S0> Ann Leary, reviewing the book for NPR, calls it "a short book about a lifetime of longing" and says "Moore uses brilliant economy in his writing; it's as if words are as scarce and precious as sunshine in this gloomy section of postwar Belfast". <P0-S1> According to Colm Tóibín, the book "is full of Joycean moments... it takes from ‘Clay’, the most mysterious story in Dubliners, the idea of a single, middle-aged woman visiting a family and finding both comfort and humiliation there". <P0-S2> Robert Fulford, writing in Canada's "The Globe and Mail", describes it as "a bleak post-Catholic novel" that depicts "a desolate life, stripped of warming humanity". <P0-S3> Set in Belfast in the 1950s, "Judith Hearne" has been described as "a sensitive study of a middle-aged alcoholic woman in drab Belfast and her desperate last attempts at finding love and companionship". <SEP> <P1-S0> the united kingdom of great britain and northern ireland, commonly known as the united kingdom (uk) or britain, is a sovereign country lying off the north - western coast of the european mainland. <P1-S1> the united kingdom includes the island of great britain, the north - eastern part of the island of ireland and many smaller islands. <P1-S2> northern ireland is the only part of the united kingdom that shares a land border with another sovereign state‍ -- ‌the republic of ireland. <P1-S3> apart from this land border, the united kingdom is surrounded by the atlantic ocean, with the north sea to its east, the english channel to its south and the celtic sea to its south - south - west, giving it the 12th - longest coastline in the world. <P1-S4> the irish sea lies between great britain and ireland. <P1-S5> with an area of 242,500 square kilometres (93,600 sq mi), the united kingdom is the 78th - largest sovereign state in the world. <P1-S6> it is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. <SEP> <P2-S0> The National Trust owns thirty-six public houses of historic interest including the George Inn, Southwark, London and The Crown Liquor Saloon, Belfast, Northern Ireland. <P2-S1> CAMRA maintains a "National Inventory" of historical notability and of architecturally and decoratively notable pubs. <SEP> <P3-S0> the dutch "1 guilder coin" struck under the reign of queen wilhelmina was a unit of currency in the netherlands. <SEP> <P4-S0> The British Crown dependencies of Guernsey and Jersey produce their own local issues of sterling: the ``Guernsey pound ''and the`` Jersey pound''. <P4-S1> The pound sterling is also used in the Isle of Man (alongside the Manx pound), Gibraltar (alongside the Gibraltar pound), the Falkland Islands (alongside the Falkland Islands pound), Saint Helena and Ascension Island in Saint Helena, Ascension and Tristan da Cunha (alongside the Saint Helena pound). <P4-S2> The Bank of England is the central bank for the pound sterling, issuing its own coins and banknotes, and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. <P4-S3> Banknotes issued by other jurisdictions are not regulated by the Bank of England; local governments use Bank of England notes as backing for local issuance by allowing them to be exchanged 1: 1 at face value.
