On the Marble Cliffs (Auf den Marmorklippen)

Blurb

On the Marble Cliffs is a different kind of book, however. It concerns two brothers, living in a peaceful forest setting, who spend their lives studying botany, enraptured by the flora around them, and enjoying the tranquility and solitude of their surroundings. But their homeland and whole way of life are threatened by a marauding band of infiltrators under the command of the Chief Ranger. Things head for a bloody climax when those who live in the forest in the shadow of the marble cliffs realise they need to make a stand and fight, or else be overwhelmed by the Ranger and his men.
