In this novel, Bella of Brockhall tells a young mouse the story of how Martin the Warrior saved Mossflower from the tyrannical rule of Tsarmina, Queen of a Thousand Eyes. Martin comes to Mossflower as the last of the woodland creatures are fleeing the rule of Tsarmina's father, Verdauga, only to have Tsarmina rise to the throne after Verdauga's death. The woodland creatures want to fight Tsarmina's rule, but they are not strong enough in number to defeat her army. However, Martin travels to Salamandastron to find Boar the Fighter and ask him to return to Mossflower and defeat Tsarmina. A great battle ensues upon Martin's return, freeing all of Mossflower. Mossflower is a riveting prequel that will satisfy many questions for fans of Redwall.
Opression seems to be the most important theme
Throughout the book it seems that the woodlanders are peaceful poeple who were taken over by invaders and were treated cruely but when treated cruel without a purpose. They banded together to fight back and free themselves from the pain and suffering of opression.
