Here is an excellent one:
Rockets and People by Boris Chertok, soviet space engineer. Translated by NASA. 4 big parts, free to use.
It's the history of the soviet space program but includes many other historical details like the war ending in Berlin and nuclear arms history. Very well written by some key engineer himself not just some ghost writer. Not propaganda but the real thing honestly written by somebody in the know.
