Best book to come out in quite a while IMO, this era is soooo much more interesting (fluff wise, not really equipment wise) to read about than the Jihad.
I read quite a bit of it, skimmed the whole thing, and I love the crap outta it.... it'll be the first BT book I read from cover to cover, every word, in a *really* long time, since the 4th Succession War Atlases I think.
The maps were great, the writing style great, the detail in listing out regiments rocked, the only thing that kinda surprised me was ammo on the caspars and drones, I kinda figured they'd be energy based units, but still absolutely superb stuff. Can't wait for more (like the FM SLDF 2750 stuff)!
