Query: Disappointing

This book came highly recommended by a source I respect, so I was surprised to find it boring. I would have been better off reading a biography of Siegfried Sassoon, and something on treatment for shell shock in WWI. The most interesting character for me was Rivers, but by the end of the book I still knew little about him. Most unsatisfactory, I had little interest in finishing this book and certainly won't be bothering with the sequels.
