It’s hard enough to write well in one genre, never mind blending two or more into one seamless whole. But Myke Cole, author of the Shadow Ops trilogy and its prequel series, the Reawakening Trilogy (which includes his latest, Siege Line), mixes zombie horror, military thriller, and urban fantasy, and makes it look easy. The cornerstone of his success? Characters that never fail to be three-dimensional people. Also: terrific pacing, and action sequences that make it impossible to stop flipping pages.
