Atlantis Books is perched high on a clifftop in Oia, a village on the north-western tip of Santorini. Two American students, Craig Walzer and Oliver Wise, came up with the idea for the shop while visiting the island in 2002. ‘We read all of our books and couldn't find anywhere else to buy some,’ Walzer told me. They returned with friends in 2004 and built Atlantis out of found objects from beaches, junkyards, and donations from the neighbours. ‘We took our time actually building the shower, because books were more important that hygiene.'
