Michael Gruber is a superior writer of mysteries which border interestingly and believably on the magical/supernatural. His detective Jimmy Paez is a Cuban who is or was a detective with the Miami PD, a man of superior intuition who is conflicted between his western rationality and something more mysterious and vaster in scope. Night of the Jaguar and Tropic of Night deal interestingly with Siberian shamanism, Yoruba magic, Amazon indian shamanism, and Santeria. Valley of Bones deals with an extreme sect of Catholic nuns consecrated to nursing on battle lines. He acknowledges and delves into matters not as "ignorant superstitions" but as valid worldviews with their own particular power. He is well worth getting acquainted with.
