The first book in a new series, The Diviners is a well-written, serial killer thriller with elements of the occult and supernatural. Set in 1920's New York, Evie is a bold, sassy, and progressive young flapper. While not always the best role model--she drinks, lies when it suits her purposes, and is occasionally more concerned with her own good time than anything else--she is strong, resourceful and smart. This is a long and involved book, with numerous storylines that overlap and come together in the end. Definitely dark and gruesome in parts, there are grisly and graphic descriptions of murders and dismembered bodies, cannibalism is mentioned, and the plot is a frightening and suspenseful one. Language is mild and reflective of the era (harlot, son of a b-tch, h-ll, wh-re). Drinking and smoking take place and pot smoking is referenced. Domestic violence involving non-consensual sex results in unwanted pregnancy and abortion. Psychic and supernatural abilities are central to the story, and a doomsday cult is the center of the evil, murderous element. Mature readers looking for a complex, scary, and historical read, and those interested in the occult, ghosts, and murder mysteries will thoroughly enjoy this story.
