I had read the
Posleen War series based on a recommendation I saw, perhaps here? I even thought the Add-ons and ones done with other writers were very good. Even the ones written with "he whose name shall not be mentioned".
However, by the time I got to the
Cally's War series, it was obvious they were out of ideas, and was starting to get "Oh John Ringo NO!!"-ish.
The
Troy series was a good and interesting read.
Von Neumann's War was somewhat predictable. (Eccentric whom everyone laughs at, saves the world.)
The Last Centurion was fantastic, despite the "Oh John Ringo No !!" part. (Which could have been easily written so it comes off less statutory rape-y.)
I only got through the first two
Empire of Man aka the "March to" series because the library can't find their copy of
March to the Stars.
Then I read
A Deeper Blue (only book in the
Ghost series that my library has and I can see why). It seemed like simply a collection of of "Oh John Ringo, NO!!". and turned me off.
