The Travel Twins and the Lost Secret of the Vikings

Twelve year old twins Josh and Hannah travel from the USA to visit their Uncle Olaf in Norway. Olaf runs the Museum of Norse Antiquities in Oslo, and the museum's greatest treasure-the Viking chieftain Leif Erikson's fabled Sunstone-is stolen. Hot on the trail of the suspected thief, the twins ride on a dizzyingly high train through the Scandes Mountains to Norway's largest fjord, a deep waterway which connects directly to the North Sea. While spying on the suspect's suspicious behavior, the twins are suddenly kidnapped on the train! They elude their captors by breaking free, sneaking across the top of the train as it chugs through a tunnel, and tricking the kidnappers. Then they learn the thief's true motivation: to use the Sunstone to interpret the coded Undredal Runes so as to re-create the Viking super-warriors known as Berserkers. Can the twins defeat the plot, return the stolen treasure, and save the world from the secret of Viking Berserkers which has been concealed for a thousand years?

My Review

This is the fourth book in this series. I have read every book. Each one has an entertaining story. This book was no exception. I enjoyed the travel to another country. Josh and Hannah were very brave for their age. She showed that if you put your mind to it that you can do anything. You don't have to be afraid. Unlike the other books in this series, this one touched on a bit of history with Viking Chieftain Leif Erikson. This added another fun element to this story. Back to Josh and Hannah. As a young reader, they will relate to both of them. Even if you are a boy or a girl; you can cheer for them both. There was plenty of action to keep the story exciting. In addition, I found that there were not too many big words that they older nephews will be able to read this book on their own with little adult interaction. This is a bonus.
