Frankly, it sucks. There's more of Traviss's Mandalorian "language" than in all her other books combined. And as it's been pointed out, it's not a language, it's just a cipher for English words, with lots of apostrophes.
Secondly, Kal Skirata is a fucking Gary Stu.
Thridly, Traviss's attitude of "Jedi, except those who agree with the Mandalorians, are evil" is spouting out of every page.
And finally, the latest attempt to justify her numbers:
(Besany Wennen, a Republic Treasury agent, is watching an analyst on the holonews):
Sigh... let's take this up. Earth's mass is about 6x10^24 kg, a quintillion is 10^18, so 40 quintillion kilograms make up 0.00067% of the planet's mass. For one planet, it may be significant. But we're talking about a galaxy with at least a million inhabited worlds. And there's no reason not to mine from uninhabited ones, in fact, it may be more efficient to do that.page 291 wrote: "Moron," she mumbled at the screen. The analyst was throwing out numbers, huge ones, and because her business was numbers she found herself reaching for a stylus and doodling a few figures on the nearest datapad. "I bet you don't even know how many zeros there are in a quintillion."
She did, though, and numbers comforted her, so she considered his argument. Then she started wondering how much metal went into a battle droid--forty kilos, at the very least--and multiplied it by a quintillion just out of curiosity, and then started wondering where all that metal came from if 90 percent of the average rocky planet was silica, and not all the remaining 10 percent was the right kind of metal, or could be mined anyway, and mining and ore processing took up a lot of resources...
On Earth, we're currently producing over 100 million tons (10^11 kg) of steel per month. 40 quintillion kilograms is (33 million) x (Earth's yearly production of steel).
Is that too much? Given more advanced technology, ability to mine asteroid fields and uninhabited planets whole, and most importantly, sheer scope, it's certainly a possible feat in the SW galaxy. (Plus, there's no reason not to think a good fraction of at least the B1 battle droids were built in the 10 years between Naboo and Geonosis, and stockpiled in preparation for the war). Are such numbers really necessary? Given that the fight is over the million inhabited worlds, probably not--same idea as that, given the Death Stars, the Empire can make a fleet of billions of Star Destroyers, but there's no reason for them to do so.
But even if quintillions of droids is exaggerated, the true number would be in the quadrillions, or hundreds of trillions at the least. Not millions.
The real stupidity of the above quote is that, while its unnatural for us to do this, a SW in-universe character, should she take up that line of inquiry, would naturally continue and ask how many planets are there in the galaxy. That she doesn't even considere this shows just how much contortion Traviss has to go through to force her numbers on the galaxy.
