The 26 chapters of this book are named after places, one for each letter of the alphabet. Moving around in time as well as location, it reads rather like a collection of short stories with a common central character rather than a novel. Rather than being driven by exposition of a plot, each episode is enjoyed as a nicely written set piece.
The writing is good - Faulks has a style which is elegant and descriptive without being overblown. Some chapters are very strong, for instance the description of office life and the chapter set in Jerusalem. Others were less interesting, although I suspect every reader would have a different preference depending on their own experiences.
It isn't really a very memorable book. I enjoyed the experience of reading it whilst I was actually reading the words, but it is not a work that has made any particular emotional impact on me. That's not to say it isn't a good read, but a book with so little long standing impact cannot, in my opinion, be great.
The writing will be particularly enjoyed by those who love language and word play - there is plenty of exploration on the origin of words, for example. I would also recommend it to those who like short stories, and its themes of 'finding yourself' and mental illness will be of interest to those with experience of these issues. Overall, I suppose I feel ambivalently positive towards the book - it wasn't a waste of time to read, but I wouldn't say it was unmissable.
