Thriller: Blood Type X, J.L. Delozier

Dr. Persephone “Seph” Smith, FBI profiler, has a box of photos. The pictures are of William Blaine, the most wanted criminal in the world, responsible for the pathogen that killed nearly 50% of the world’s population. She caught him, once, but he escaped, and someone has now sent her a box of photos of him. The clues lead her and her partner first to France, then to the Basque region of Spain, once again on the trail of the evil genius.


Author and doctor J.L. Delozier has created a fierce and wonderful heroine in her trilogy of books about Seph Smith. We first met Smith in Storm Shelter, then saw her confront Blaine for the first time in Type and Cross. Now, her battle with Blaine sometimes takes second place to her battle with her own demons. Too many losses, too many bodies, have sent Smith to seek refuge in alcohol. It may numb the nightmares, but it does not remove either the pain that haunts her or the criminal that awaits her. Seph has a heightened sense of empathy. She is able to sense the emotions of others–which in a time of catastrophic death is an almost crippling challenge. This gives her an advantage in developing a profile of criminals, but can make it difficult living her daily life.


Delozier’s medical experience informs her writing without making it overly technical or dry. She never forgets her plot or her characters when dropping in details about the reactions to chemo drugs and other medical details. I will admit to wondering at one point whether she had either witnessed a taser or possibly experienced one herself (no doubt in the desire to get the details correct and not from any unfortunate interactions with the police).


Her descriptions of the settings are also vivid. Whether she has actually visited the areas in her books or has successfully used her research to picture the locations in her mind, she effectively lets the reader see France and Spain through her writing.


Delozier is a local author and one of the leaders of the Nittany Valley Writers Network (State College, Pennsylvania). She is also a friend of ours. That being said, we only review books we like–even when friends write them. We like this book.


A flawed but triumphant heroine. A brilliant and psychopathic enemy. The beauty of Europe. J.L. Delozier’s latest thriller has it all. Read all three of the books to get Seph Smith’s full story, and enjoy.


J.L. Delozier will be at State College’s 2019 PA Bookfest on Saturday, July 13, 2019. This week we are featuring authors who will be part of the bookfest, part of an annual tradition we started last year celebrating authors who are from our local area.

One thought on “Book Review: Blood Type X, J.L. Delozier

  1. Read all three. Great series. They do make you wonder just how much is fiction, or how much has been from experience. Recommended to friends.
