What is the author's style in The Broken Bridge by Philip Pullman?

Since Wales is a country within the United Kingdom—it is located between to England and the Atlantic Ocean and Irish Sea on the other—a British accent and manner of speech is apparent in the dialogue of the novel. The author uses British slang, such as the words "bloody," and "duw annwyl" in the teenagers' conversations. When reading the book, there is an British accent to the words the characters speak; the reader can actually hear the accent.
