Saga of Tanya the Evil (LN) vol 5
This series is always difficult to read because of the long volumes, military jargon and the often multi-layered or unclear meanings of a lot of the text. Particularly the protagonist's internal monologue. Always worth it though, in my opinion, as it's a pretty unique LN in a lot of ways and a genuinely enjoyable read.
This volume in particular does some nice stuff. For starters, it's becoming clear that the Empire can't afford a Total War situation against the rest of the world for too long. The recurring theme here is the increasing lack of veterans and the sacrifice of the nation's young people. Further, for possibly the first time the 203rd Aerial Mage Battalion takes some serious damage with little to show for it. Sure, they make a bit of a comeback from it, but it's clear they're on the back foot.
There's also an interesting little bit towards the latter part of the novel where Serebryakov (sp?) ruminates on Tanya's magical ability, answering a question I've had since near the start of the series. Turns out she doesn't have any oustanding magical capacity (barely above average, apparently) - her most ridiculous feats are a combination of iron determination, training and a helping hand from Being X in getting the Type-95 to work.
So yeah, another good volume for a good series. Even with the "twist" at the end it looks like things are only going to get grimmer from here on out.
