Raidho. Un viaje con los vikingos

After his adventure in ancient Egypt, Víctor travels back in time again.
This time, the green beetle transports him to the age of the Vikings.
Shortly after arriving, he is captured and enslaved by Asgerd, a young
female warrior. With Asgerd and her family, Víctor sets out on a trip across
the sea that will lead the Vikings to discover Greenland.
