Description
Everyone sees the house they want to see…
Paris, 1900: Amidst the decadence of the Belle Époque, American heiress Lydia Temple falls in love with ethereal aristocrat Séraphine de Valleiry and builds her a whimsical castle in the Swiss mountains. The Chateau des Miroirs becomes a bastion of spiritualism until it is taken over by sinister forces during the First World War. And then it disappears. Or did it ever really exist?
Oxford, 2035: Elderly professor Cyrus Field is rapidly losing his sight and his will to live, when student Haydn Young presents him with a collection of letters previously lost to history. These letters may contain the answer to the philosophical problem that has been his life’s work. But does he really want to know the truth? With war closing in, Cyrus and Haydn must decide whether to risk everything in the quest for knowledge.
The mystery of the Chateau des Miroirs reverberates through the generations, connecting two souls that are destined to find each other.

5 stars! ⭐️⭐️⭐️⭐️⭐️
This book was interesting, atmospheric, chilling and so beautiful. It is a gentle horror story but it’s also so much more than that, it’s a story about love and what it means to be running out of time.
What I loved in particular:
- the author took the idea of mirrors and masterfully dispersed them through the story. Lydia and her friends and preparing for the onset of the First World War and in 2035 the characters are preparing for an apocalyptic war. Cyrus’s life in 2035 is almost a mirror of his life in the 1980s, right down to his academic rivalries and love interest. By the end of the book I was trying to find plot reflections everywhere.
- the setting, I went to uni in Geneva and Catherine Fearns has perfectly captured the beauty and the appeal of the city and its surrounds.
- I liked the detailed scientific theories that were put forward by the characters to explain the supernatural. I also loved the use of Haydn’s essay to explain potential plot holes because I too was wondering why extensive correspondence with Carl Jung wouldn’t have been discovered before.
- the ending, I don’t include spoilers in my reviews so all I can say is that it was both chilling, sad and beautiful.
The Fault Mirror is one of those books that I will still be thinking about years after finishing.
Thank you so much to NetGalley and Quill and Crow Publishing House for the opportunity to read this ARC.

I just finished this book and I am crying. That was such a beautiful love story. The way this story unfolds sucks you in and keeps you locked in from beginning to end. The whole concept is interesting and the way the imagery and sensory hits you is incredible. I truly imagined myself in Cyrus' shoes, and his increasing blindness. I almost wish it didn't end because I want more, but its truly perfect as it is.
In letters to her friend and doctor, Lydia details how she's fallen in love with Seraphine and becomes inspired to build a fairytale mansion on a mountain with another mountain that reflects like a mirror next to it. As they settle in and start hosting friends, strange things start happening and changing around them.
Cyrus is given these letters by a mysterious student and challenged to find out why Lydia seems to have been erased from history.
