It's simply told, but the story itself is anything but, even today. It presents kinky and non-monogamous relationships for the whole world to see and, more importantly, to understand. It doesn't go in depth, but it definitely is compelling. It doesn't contain any action, but it doesn't have any flaws either. A quiet strong romance. A solid biography.
Rebecca Hall and Bella Heathcote.
