Sons and Lovers by D.H. Lawrence

This is a very good book! I like the mix of tragedy and dry humor-- though I'm a bit confused at what the story is "about"-- initially I thought it would be about a woman having an affair (a popular D.H. Lawrence theme), but then the woman got older and it was more about her sons (which makes sense-- the title and all), but then it started talking about the daughter.... and so far there aren't any lovers! :)
However, I'm only about halfway through the book. It is quite good, and I'm enjoying it... I'm just a little lost as to where the story is going.
