This remarkable novel reminded me of The End of Mr. Y and Our Tragic Universe, by Scarlett Thomas. (Thomas is one of my Top Shelf Authors = I Want To Write Like That When I Grow Up.)
An unusual blend of the esoteric and the practical, the book follows a pianist diagnosed with RSI (Repetitive Stress Injury). Her curious condition and an accidental encounter peel back various layers of memory, truth and trust, revealing rather more than she expects. Both reader and narrator are left with more questions than answers, but plenty to think about.
As a sufferer of RSI, I sympathised with the narrator and her frustration at being unable to express herself in her own art form. But most of all I was incredibly impressed by a writer of such skill and confidence. She dances between plausible reality and the shadowy realm between truth and perception. Highly recommended.
