Tim O'Brien is an award-winning writer and I have really enjoyed some of his other novels. This is his first, written in 1975. I recommend reading Tim O'Brien, but don't start with this one. You may get turned off early and miss out on something really good. After slogging through the first half of this book, I almost pitched it. Nothing happens, even when there is a big buildup to make you think something is finally going to happen. The writing style is poor. There is endless repitition, uninspired description "It was very hot," bad grammar and other irritants.
THEN, I read the second half and was plunged into an action-adventure-survival drama with two brothers fighting for their lives in a whited-out northern Minnesota forest in January. The style didn't improve, but I didn't care. In many ways this book seemed to me the forerunner of his bestseller In the Lake of the Woods, which I highly recommend. Don't pass this one by, either. Skip or skim the first part if you feel the way I did. He gets a lot better as he goes along.
