Evteev - Chelomei Trilogy???

[David Lee Rickman]

Who can tell me the differences between the books, "?5@560O 2@5740B5;O< 8 8A?KB0B5;O< @0:5B=>-:>A<8G5A:>9 B5E=8:8 ?>A2OI05BAO)" and "?5@560O 2@5  ..'5;><5O. !>740B5;O< 8 8A?KB0B5;O< @0:5B=>-:>A<8G5A:>9 B5E=8:8 ?>A2OI05BAO" and ">;>B>9 D>=4 0:045<8:0 '5;><5O : 4>:C<5=B0;L=K5 >G5@:8"?

Are the first two essentially the same book or are there differences?

Thank you!
