evil Highborn who is planning to cause a volcanic eruption. If they fail, most
of Europe will be blanketed in ash and dust, leading to massive loss of life
and altering the fabric of European society for a generation. But to get to
Ember, Britney, Avril and Silk must navigate rivers of lava, sulfurous caverns,
and monsters borne of fire.
