Something catastrophic has happened to the earth, the seas glow with green life that eats and destroys all it comes in contact with. The earth is covered with Ice and the people who are surviving live like early cavemen. The animals are prehistoric as well, mastodons, lions, saber-tooth tigers, wolves and Dire wolves. There is a constant threat from the animals , the freezing temperatures, the dangers of attacks from other tribes, starvation and extinction.
The author has created a beautiful world of snow and ice, mountains and oceans in which her characters live and thrive. The characterizations are vibrant and real and the reader becomes the cheering squad for the survival of each of them. There is an underlying hidden story of the people who were alive before and what they tried to do to save the earth from boiling climate change and reintroduce man and animals that would survive in what the earth had become. This is a beautifully scripted book and I enjoyed reading it. The author also left an opening for more of the story , so I hope this will be a series.
