Day of the Dead was number eight in the Navajo Nation mystery series. I read the first seven. The main plot of this installment revolves around the drug war between the Sinaloa and Sonora cartels. The main ongoing characters of the series; Charlie Yazzi, Thomas Begay, and Harley Ponyboy get pulled into the drug war. The tribal liaison officer with the FBI, Billy Red Clay, plays a more prominent role in this book. FBI agent Fred Smith, and DEA agent Bob Freeman are also key characters in the storyline. Tressa Tarango and Abraham Garza are the focal points of the plot. Both work in a Mexican restaurant in Colorado for Hector Espinoza, a distributor for the Sinaloa cartel. Hector's nephew, Carlos, is a lawyer, who swindled Tressa out of money and provided bad advice to her husband, Luca. When Luca escaped prison, he landed on the Navajo reservation and murdered several people, before he himself met his demise. Tressa sets out to retrieve Luca's ashes in order to return them to Mexico, and she enlists Little Abraham in the enterprise. I'll stop there. I rate this book as one of the better ones in the Navajo Nation series. It moved along at a decent pace. and it had a fairly suspenseful ending. The development of the Tressa and Lil Abe characters was decent. A subplot involving the interaction of the DEA, FBI and tribal characters added to the interest. As always, the author weaves in the Navajo culture and beliefs. I plan to read book nine.
