Willa Cather has come highly recommended, but I'm only now getting around to reading her work for the first time. I see why she was recommended. The writing is my style: poetic and intelligent without losing focus on the story. I love that. I think I'll be very pleased reading her work in the years to come.
That being said, this story was a little too dry at times. I loved the language, and I liked the characters (though they were slightly formulaic), but I'd like to have seen a little more movement, a little more ambition. O Pioneers! was only Cather's second novel; I have high hopes for some of her later novels.
