This second book was just as good as the first book, and a very quick read. I sat down and put it away in and hour. Lug is awakened one morning by Crazy Crag who wants him to look at something. He pretends to be asleep. Crag wakes his whole family when he fails to wake Lug. Crag wants them to come see something. No one moves until Crag has left and they hear a loud booming noise. Lug and his friends Stony, Echo, and Wooly all climb the mountain to find Crag. What they see is a giant glacier moving really quickly their way. On their way to find out what they can do to stop it, they find a boy under ice. They thaw him out. He tells them his name is Blast and he lives on the glacier. He tells them the glacier will soon crush their caves and he is offering them a place to stay with him. A message is sent back to their village as they check out the glacier.
For some reason, Lug just doesn't trust Blast. He soon learns he as a good reason not to. Blast is up to no good and it is up to Lug to figure out a way to stop him and the glacier. This book is sure to keep students on the edge of their seat flipping pages. I do hope there are more to come in this series.
