Ok, now I’m less confused. I read that book about 20 years ago and couldn’t remember anything about squares and triangles. That explains why that had been mentioned.
Empire from the Ashes by David Weber
I mean, c’mon! The whole thing is a protracted space battle… (more or less)
Starships the size of the moon (good guys) vs millions of other starships kilometers in length (bad guys) using weapons capable of obliterating planets against each other…
… oh man… I would SO love to see those battles on a screen…
One specific attack has a fighter launching a missile that can hyperspace within atmosphere and pop back into real time right before impact. Hard impact on a ground target by a solid object that travels at .8c as it crosses back… Big boom… very big boom… damn that’d be sweet.
Good read to boot. (well if you don’t want anything particularly deep thought provoking at least)
