Zodiac’s Shadow (GKP Mysteries - Another Mystery to Thrill Series 2 Book 12), my fifty-seventh read from author Grant Kelly. An informative 32-page short read. “I received a complementary Kindle copy of this book and am voluntarily leaving a review." The gifting of this book did not affect my opinion of it. I look forward to reading more from this author with GKP Lost Treasure Series: Illustrated Edition - Volume 3 (GKP Lost Treasure Series - Illustrated Editions) high on my TBR list.

The Zodiac's "reign" was a scary time for me. I had just graduated from high school in 1968. I was in the workforce dating strong. He was targeting couples out on dates. Luckily, he was in California; I was in Nebraska. But he made national news. His case is still open..........

I was gifted an Audible version of this book from the author through Story Origin. A short 25 minute listen but offers a good introduction to the Zodiac killer. Creepy facts. So many unanswered questions.

The digital voices of Mary G. is perfect. Enough inflection, it sounds live.

Audiobook: I was entertained by this brief overview of the mystery surrounding this serial killer. Although there was much more to the story, this recap presented some of the salient points which brought to mind the scariness of that time. I thought the digital narration by Mary G was to understand and to follow. I was given a copy of the audiobook. I volunteered, without financial gain, to post this review which reflected my honest opinions regarding this audiobook.
