This is the third book in John Boyne’s Elements quartet and it’s the darkest and most powerful so far. Each book can be read as a standalone story, but if you’ve read the previous two – Water and Earth – you’ll see some links between the characters and plots. I would still recommend reading them in order if possible, although it’s not essential.

Fire, like the other books, is novella-length – in this case 163 pages – but as usual, Boyne manages to pack a huge amount into those pages, more than you would often find in a much longer novel. Our narrator this time is Freya Petrus, a renowned surgeon who works with burns and skin grafts. She’s only in her thirties but has already established herself as one of the best in her field. What Freya gets up to in her private life, however, is much less admirable…in fact, it’s horrible. To understand what has made her the person she is – both the good side and the bad – we have to go back to Freya’s childhood and witness the traumatic experiences that shaped her future.

It’s difficult to really discuss the issues a book like this raises without spoiling things, so I’ll just say that what Freya experiences as a child leaves her badly damaged and, in her mind, justifies the harm she does to other people as an adult. I did have some sympathy for the young Freya, but that was surpassed by the loathing I felt for the older Freya. John Boyne is never afraid to tackle unpleasant and controversial subjects in his books, but the things Freya does are particularly shocking and I found it a very uncomfortable book to read. It’s also fascinating and completely gripping, so I do recommend it as long as you’re prepared!

As with the themes of water and earth in the previous two books, the element of fire plays a part in this one in several different ways: not only does Freya work with victims of fire, it could be said that she’s also playing with fire in her personal life. Other important themes running through the story include the question of nature versus nurture and which has the biggest role in forming our character, the level of responsibility each of us has to do what we know is right, and the different expectations society has of men and women. It’s a book that leaves you with a lot to think about after reaching the final page.

Although each book in this quartet does work on its own, a minor character from each one becomes the main protagonist of the next. It seems that Aaron, who works with Freya at the hospital, is going to be the star of the final book, Air. It will be published in May 2025 and I’m looking forward to seeing how Boyne brings the series to an end.
