The poems in (Un)belonging explore physical and psychological spaces, examining the consequences of a life lived on three continents, defined by separation from homelands and loved ones, shaped by departure and return, and the evolution and multiplication of identity. Throughout the collection, the setting continually moves from Australia to Ireland to the United States, making stops in England, Iceland, Greece, Italy, New Zealand and Slovakia. O’Reilly’s poetry engages with a range of concerns and obsessions, including identity, belonging, expatriation, immigration, exile, ancestry, landscape, alienation, homesickness, suburbia, fatherhood, nostalgia, death and grief … finding beauty, contentment and joy amidst an elusive quest for home.
