That obviously means its very exciting, very well written and keeps you on your toes. It follows a structure very similar to tis predecessors and so in that way gives few surprises. However, this book has more twists and turns than something very twisty and turny, which means that a certain amount of concentration is needed when reading it.
The characters are developed better than in his previous books, showing how his talent as a writer has grown as he has written more books and they are generally believable, even if the whole story is a little bit larger-than-life. Even so, it is clear that the author knows the subject (anaestheticts), which makes the book read smoothly and seem more real.
A thoroughly enjoyable and entertaining book, and even if it doesn't do anything to make itself stand out from all the other books the man has written, it is still worth reading, just like most of his others.
