Such a complex plot but it does intrigue. This is a story of memory, contrasting Norval who has the precise memory of a synaesthete and his mother who he attempts to nurse through Alzheimers and it is all bound up with the drugs which might help, might heal or cause more damage. Whilst the protagonists fought confusion so did I as the reader. Personally, I preferred Jules Hardy's Altered Land. But this book is probably much cleverer.
