Harrison has a voracious appetite for three things: the outdoors (ie. hunting), poetry, and cooking and eating obscene amounts of fatty, rich food (mostly of the wild game, organs, and head cheese variety). His writing is assertive and manly -- think Hemingway on the Food Network.
I've known people who can't stand Harrison's books and think he's a pompous arrogant lout. I, on the other hand, love this book and am fascinated by the way Harrison approaches life (and his food) with a profound, unapologetic gusto. I tried his poetry and couldn't get into it but I suppose I more than make up for it with my affinity for this particular book.
This book is definitely not for the faint of heart or those who prefer their food writing more on the Julia Child side of things. If, however, you are more adventurous in spirit and can keep up with the savage passion by which Harrison lives his life and eats his food, then this is for you.
