Although the entire book is written in the modern way, it is easy to read as well as lyrical. It brings the reader into the world of spirits and beliefs of the indigenous people of America. It tells the tale of two brothers and how one of them led their people from the icy cold of Alaska to the south where climates are warmer and food is plentiful. It tells the tale of the perilous walk through a crack in the icy glacier with the help of the Wolf Spirit.
It has all the ingredients for a good book : suspense, treachery, romance (not the mushy kind lah!) and mystery of the unknown spirit world. The book is a standalone version so one need not worry about having not read all the books in order.
The beginning of each book starts off with a scene from the modern world and how modern day society views the traditions of these indigenous people. It always describe a conflict of beliefs and how humankind can be selfish and disrespectful of another person's belief. After this introduction, the story begins and it is hard to put down the book after that.
