This is listed as a prequel to a series I haven't read. If memory serves, I won a copy at a giveaway at DragonCon some years ago. I'm not entirely sure what to make of the book. It might make more senes if I'd read the series, I suppose, but then, shouldn't prequels be able to stand alone?
Ben (odd name for Roman times) Stiger comes from a powerful family fallen on hard times when the head of the family backed the wrong side in a civil war. Being a second son, Ben decided to go into the military. He starts off as a kind of stuck up, self-centered officer, newly assigned to the 7th Company, Third Legion. As the book goes on, he realizes the men assigned to him are actually people, and vows to actually serve them.
While there's an enemy force to deal with from the Rivan Army, his biggest foes are an incompetent captain and a suck-up bully of a sergeant. Stiger does his best to work around them to make his unit the best, and gets treated horribly, both by the idiotic officers and the people who doubt him because of his family history.
Naturally, he falls into the right place at the right time, and manages to save the newly arrived general and his beautiful daughter. She seems like she'd be a love interest, but she's in something like three short scenes. Stiger also finds a previously missed ford across the river to get to the enemy, which his superior naturally does nothing about.
The big fight comes, Stiger's ford becomes hugely important, and most of the bad guys get what's coming to them.
Oddities in the book include the troops drinking coffee (which, far as I know, didn't start until the 15th century or so), the guy's name (Ben just sounds wrong, even if it's historically accurate, which I admit I don't know), and the hinted at more than seen existence of magic. There are no spells or anything, there's just a passing reference to a magical lantern and a holy paladin who can heal. There's an epilogue that doesn't really make any sense to me, but that, too, might tie in to the larger series.
Decent read, just didn't hugely grab me.
