Deep in the ocean, far beyond the reach of even the brightest sun, the earth quakes. Hagfish scatter and snailfish flutter. Lava pillows flash and fade, rumpling the seabed as a new volcano births a mountain. Where hot meets cold, a chimney forms. Here begins a colony of unexpected creatures. Other chimneys grow and cool, grow and cool, while the mountain stretches ever upwards. A rumble becomes a roar and the sea boils. Lava fireworks the sky. A new island is born.

More volcanoes erupt under water than exist on land. In the vein of Iceberg and Tree - combining deep scientific research, lyrical language and stunning illustrations - Volcano is the next exploration of the natural world from the CBCA award-winning team of Claire Saxby and Jess Racklyeft.
