Low Life is a very difficult book to review, you will either love it or hate it and to write too much about the novel will certainly not be helpful. If you like transgressive fiction e.g. Palahniuk; whereby the protagonist are rebelling against the basic norms of society, they may seem mentally ill, anti-social, or nihilistic; you will certainly enjoy this book.
