The daylight hours were growing shorter, but we took our leave of Iceland before the true onset of winter, when the country would be plunged into a period of almost unbroken darkness. For us, Iceland was all about the light. A light which powered long summer days. Which illuminated vistas of mountains, fjords and waterfalls. Which fought through clouds to reflect off a glacier and momentarily blind us. This light, shining on a country that didn't need anywhere near 91 days to work its way into our hearts.
