What is the author's style in American Subversive: A Novel by David Goodwillie?

The novel is written using mostly exposition, with a minute amount of dialogue, as Aidan and Paige recount the past events described. This distribution is useful because it allows the novel to focus on the story as a whole rather than inconsequential details. It also serves to characterize Aidan, Paige and the other characters in American Subversive.
