What is the author's style in The Rifle by Gary Paulsen?

Author Gary Paulsen's prose style is spare and detached, and sometimes because of this he is able to make use of a certain dry irony. For example, the narrator notes with characteristic matter-of-factness that Tim Harrow, who spent his entire life convinced that ownership of guns was essential to individual liberty and self-defense, was in the end the victim not of a burglar or mugger, but of stomach cancer, a villain that guns can do nothing against. Similarly, the narrator painstakingly records the long journey of the Rifle and how many people after John Byam handled it, and then simply notes that no one ever checked to see if the Rifle was loaded.
