Twins Noah and Emma and their volcanologist father have traveled from Hawaii to spend a year in Alaska.  Noah thinks Alaska is the most boing place on Earth and cannot wait to return to Hawaii.  Their dad wants to take measurements on a dormant volcano on an island and Emma wants to see an eagle’s nest.  Their neighbor, Alex, goes along as a guide.  Almost immediately, the mountain begins grumbling and before they know it, they are in real danger.  They race back to the boat, hoping their dad has made it back as well.  Throughout their rush, they encounter quaking, poisonous gases, choking ash, sticky mud flows, and molten lava.  The action is fast and the story is sprinkled with many volcanic facts.  Additional volcano information is found in the back.  Fans of the “I Survived” series by Lauren Tarshis will be attracted by this and other books in the “Disaster Strikes” series.
