"After spending sufficient time inside a lighthouse, who wouldn't begin to hear a song in the sound of the machinery, a voice in the wind or the waves?" Far from home, in the confines of a dim New York apartment where the oppressive skyscrapers further isolate her, Jazmina Barrera takes the reader on a tour of her lighthouses--those structures whose message is "first and foremost, that human beings are here." Starting with Robert Louis Stevenson's grandfather, an engineer charged with illuminating the Scottish coastline, On Lighthouses takes readers on an artful tour of lighthouses from the Spanish to the Oregon coasts and those in the works of Virginia Woolf, Edgar Allan Poe, Ingmar Bergman, and many others. In trying to "collect" lighthouses by obsessively describing them, Barrera begins to question the nature of writing, collecting, and how, by staring so intently at one thing we are only trying to avoid others. Equal parts personal memoir and literary history, On Lighthouses takes the reader on a desperate flight from raging sea to cold stone--from a hopeless isolation to a meaningful one--concluding at last in a place of peace: the home of a selfless, guiding light.
