Eight Cylinders is just one of several in the Jason Parent portfolio. Parent has authored books in many genres, including: science fiction, horror, thriller, and speculative fiction, among others. I reviewed another of the author’s books, Apocalypse Strain (a horror/thriller), in 2020 and found it to be quite an interesting read. Eight Cylinders (speculative fiction) is quite different from that book in many ways, though not any less interesting. I have chosen a mini-review format for this book for two reasons: it is a novella (right around 100 pages), and because it is so short almost any pieces of information I will get into spoiler territory; so the less I talk about the book directly, the better.
