Zheleznye volki - Kudriavtsev Aleksandr Valentinovich

The war came to the doorstep of the house of Prince Ratmir and his impoverished genus Iron Wolves. You need an old fortress with a handful of people from the pack of Vikings to defend. Night evil with winter cold wakes up.
Alot of trials awaits someone who is not afraid to accept the challenge of a sea conung in a cloak of human skin.
But the young warrior Ratiyar, the son of Ratmir, knows that a difficult fate is necessary to defeat it.
