A chapter in The Believer's Read Hard book, entitled 'Like Cormac McCartney, but funny' by Ed Park, inspired me to seek out this book. And a very favourable quote on the cover by Roald Dahl, told me that I was going to enjoy this book very much. A fantastic monologue of Mattie Ross detailing her quest to avenge her father's death. I will now seek out the two film versions to see how they compare.
