[Marxism] Alfred Doblin query

[Louis Proyect]

Has anybody read these? They have not been translated into English, as 
far as I know. From the Doblin wiki:

His "Amazonas-trilogie", three novels describing the onslaught of 
Europeans on the native cultures of South America, was published in 
exile in 1937. The three parts are Das Land Ohne Tod (The Land without 
Death), Der Blaue Tiger (The Blue Tiger), and Das Neue Urwald (The New 
Jungle).
