Justin Isherwood's got a kind of chewy way with words - I want to read everything out loud, just to hear how it sounds and get a better handle on the prose. But I don't mean that to sound too snooty, because he's mostly writing about cows and jackknife, chores and climbing trees.
I picked this up because author Michael Perry referred to Isherwood in a blog post, and you usually don't do too badly when a favorite writer recommends another writer. There's a lot to compare and contrast between the two: animals, ethics, simple living, and an educated way with words to describe some pretty basic things. Not to say they're the same - Perry's probably more accessible, but he'd be the one to tell you Isherwood's more authentic.
