In Iceland, volcanoes line up like pearls on a string. In the mountains and valleys the ground boils. It smokes, hisses and bubbles. Although rising from the sea as a bare lava island, life thrives on Iceland's volcanic slopes. Whether in icy heights or abysmal crevasses that tell of the fact that the earth is tearing apart here, between the North American and Eurasian tectonic plates - Iceland is a natural paradise. Magical Iceland: Living on the World's Largest Volcanic Island is a testament to the island's unexpected biodiversity and spectacular landscapes, both above and below the water.
