I went to Spinalonga in Crete a few years ago. It's an island just a few miles from Elounda and it is a former leper colony. We went on a boat trip to the island and the tour guide took us around the small village, showing us the houses, church and the small graveyard. The island itself is beautiful, but it was still strange to go there and be told of people who were sent there, believing that they would never leave (which unfortunately was the case for many). It ceased functioning as a leper colony in 1957 and is now a tourist attraction and a site for archeological digs and such.
The Island is about a family from Crete affected by leprosy and the impact it has on them, with the mother and daughter both having the disease. It's a work of fiction, but it covers such things as the German occupation of Crete during the Second World War. The description of the island reminds me of being there.
