The book is set in post-Apartheit South Africa of the 1990's. It focuses on a professional, white, middle-class couple and their attempt to come to terms with their son being accused of murder. But be warned, little actually happens and the entire plot could be summarized in one paragraph.
My main problem with this book is the language and style of writing. For me, reading the book felt like trying to run through molasses - the language is sticky, labouring and dense. I was exhausted after every page. Because the language is so heavy and distancing, I never felt a connection with the book's characters and struggled to get into the book (let alone finish it). I do think however that the feeling of distance and alienation the language created was very deliberate on the author's part, rather than a stylistic short-coming.
On one level the author's writing reminded me a little bit of Gabriel Garcia Marquez's writing - like Marquez, Nadine Gordimer is clearly a literary genius, who thinks through every word she uses and has a phenomenal understanding of language. However, Marquez's books manage to grab me despite the difficult language, whereas Gordimer's The House Gun did not.
Perhaps it sounds like a bit of a contradiction, but despite not enjoying the book whilst I was reading it, I was actually happy to have read it by the time I finished and felt I had learned something. For example, there are a lot of underlying references to South African politics and society, the black-white and rich-poor divide. I found watching the movie Tsotsi prior to reading this book really helpful as it gave me some background knowledge to life in modern South Africa.
Overall, this book had the potential to be great, but ended up being a bit of a disappointment instead. To anyone thinking about this book my advice would be: Do read a book by this author, as she is a good writer, but don't go for The House Gun.
