Billy Summers by Stephen King

Many readers who approached this book with broad-minded expectations have been quite disappointed.
While it is readable, the split into parts does not help; the story within the story, which could have been a brilliant ploy, has not fully succeeded.
The beginning suggests a multiplication of the protagonist's personality, but this is soon abandoned. The secondary characters are kept too far from the background, and some sections are very "American" and even respectable.
The second part of the novel is more, but the event dynamics are weak, hasty, and poorly executed despite the length of the pages.
