The Anabasis

On the one hand, this is a classic. On the other, it's a disjointed mess. I'm not even sure it's this particular translation -- Xenophon is occasionally mentioned (in passing) in the first half of the book, before being prominently featured in the second. This isn't an epic (so there's no divine intervention), but there's a lot of sacrifice -- Xenophon will hardly leave his tent without having the diviners tell him what he should do.

It's one of the original adventure stories, but I would not recommend it.
