"Death by DNA" eBook was published in 2016 and was written by Pierce Roberts. This is Mr. Robert's first publication. 

I categorize this novel as ‘PG’ because it contains scenes of Violence, Mature Situations, and Mature Language. The story is set primarily in contemporary Europe and South America. The primary character is Tom O’Dell, a rural Wisconsin dairy veterinarian. 

Something is causing animal specie deaths across the world in small localized areas. O'Dell is one of many vets across the country that are drafted by the USDA to investigate. They are sent to Atlanta for training and there he meets the lovely Dr. Kate Vensky of the USDA. Not long after the training, over 200 cows and heifer calves are found dead on the Fort Peck Indian Reservation. While there investigating, O'Dell and his colleagues meet a Lakota Sioux shaman who has seen a vision of a 'Destroyer' coming. 

As their investigation continues, they suspect that the cause of the animal deaths is the result of an invention originating in Nazi Germany. It becomes a race as to whether they will find who is behind the plot before the killing becomes widespread and targeted at humans. As they proceed, they find that their investigation and very lives are under threat from Nazi sympathizers. 

I thought that the 11+ hours I spent reading this 433 page thriller were interesting. The story combined romance, religion and the paranormal as well as some science fiction. While I liked the overall plot, I think it could have been given more intensity. Likewise, I think the characters could have had more depth to them. I think better cover art could have been chosen. I give this novel a 3.5 (rounded up to a 4) out of 5.
