When a writer starts an ongoing series of novels, their plan is often for the books to all be about the same character or organization, and for the novels to all have the same style or genre. But in talking to writer David Mack about his new Dark Arts series, which kicks off with the occult World War II tale The Midnight Front (paperback, Kindle), he explained that not only will every book in this series be a self-contained, stand-alone novel, they’ll all employ a different literary style as well.
