Galion resident John Caldwell said he used his police experience to add realism to his novel about the blood moon prophecy.

According to scholars, the blood moon prophecy is a series of four consecutive lunar eclipses, coinciding on Jewish holidays – with six full moons in between and no intervening partial lunar eclipses. Christians believe it’s a sign of the end of the world that is described in the Bible in Acts 2:20 and Revelation 6:12.

The first blood moon was on April 15, 2014 during a total lunar eclipse. It was the first of four consecutive total eclipses in a series, known as a tetrad. The second one took place on Oct. 8, 2014, the third one on April 4, 2015 and the remaining one will take place on Sept. 28. It is one of eight tetrads during the 21st century.

“I was in law enforcement for three years as a Deputy Marshall.” Caldwell said, declining to mentioned where he worked due to security reasons.

The book is based in Ohio and follows Investigative Unit Agent Tom Price’s investigation of a series of deaths. According to Caldwell, the plot has Price navigating the secluded foothills of southeast Ohio and the mysterious town of Irving Hills to solve his case before the blood moon rises and another life is taken.

Caldwell said he had recently started the first draft of his book when he read an article about the first of four blood moons happening.

“I thought it would be an interesting motive for a story,” Caldwell said, “So I began to incorporate it into my book. My goal is to write a book I’m not ashamed for my parents or grandparents to read.”

He said he excludes profanity, graphic violence, and sex in his stories.

“I try to add some procedural aspects in my stories.” Caldwell said, “Unfortunately, police work is not portrayed realistically on television very often. I try to add enough information to make it realistic, but not too much to make the story dry or boring.”

Caldwell is originally from Marion County and a graduate of Mount Vernon Nazarene University.

The book is available in both print and eBook editions on Amazon. Caldwell’s web site is at www.authorjohncaldwell.com and his Twitter handle is @authorjcald1.
