Rate this book
A haunted mansion with a deadly past.
A ghost-hunting robot built to uncover the truth.
An exorcist terrified of what machines can become.


After surviving the Michael incident, Father Frank Callum vowed he’d never stand beside another synthetic occult investigator. But when the Vatican orders him to oversee LUX—a cutting-edge spectral detection unit—on its first field test, he has no choice.

The the secluded estate of missing tech visionary Gideon Vale, a place whispered about in Silicon Valley for the things he experimented on before he vanished. And as the investigation begins, Callum realizes the house isn’t just haunted—it’s waiting. And LUX may be exactly what it’s been waiting for.

Perfect for fans of The Pope’s Exorcist, Sinister, and The Conjuring. A must-read for readers of occult thrillers, exorcism fiction, and supernatural horror suspense.

What Would Happen If Robots Ruled the World?

Small backstory:

Father Callum is back in this book with a new task set before him as things went wonky in the last book. A new robot (Lux) has entered the picture that was created to fight the forces of supernatural evil and is supposed to be the ultimate ghost hunter.

However when Lux is set forth in one of the most haunted mansions in Silicon Valley things do not go as planned as the evil entity of the mansion wants to take over Lux and create an army of evil robots, but Father Callum stands in the way of the forces of evil - can he stop the entity before it is too late?

That is about all I can hand out with a small backstory so if you want to know more then go read this book and series!

Thoughts:

Once again author, William Massa slowly pulled me into this book as once again I thought I could just read a couple or so chapters but the story starts out a little slow with world building but it doesn't take long before I am slammed right back into the story that continues on from the first book!

After the 30% mark the story picks up speed to the point that I read about half the book in one sitting as things go from calm to action packed within just a few chapters! I was barreling along at the speed of light as I read this book in about two days and could hardly put the book down!

The characters come alive on the pages of this book and the evil villain ghost pulses with pure evil as it becomes the focal point in the latter part of the book. I was glued to my kindle and the book fueled my insomnia as I careened along at a high rate of speed!

I am planning on reading book three in the series shortly as I don't want to lose momentum with this series as book four will be out at the end of this year. Another great book by this author and I am looking forward to reading some more of his books in the future. Giving this book five "Occult Robotic Terror" stars!

Fantastic

Wow couldn't put it down. Finished in a few hours. Another robot built Lux is supposed to be better than Michael but it wasn't. Can't wait for the next book. But unfortunately have to wait a whole year for it.

Scary blending of demonic, ghost, and robot horror. After surviving an attack by a possessed android, Father Callum is sent as an observer on a ghost-hunting expedition involving yet another robot. Supposedly superior than its predecessor, Lux isn't equipped to deal with a high-tech haunted house, site of horrific crimes and occult practices. Callum doesn't have much to do for most of the story except swing his crucifix around, warn the rest of the team, and try to survive the supernatural tsunami. Psychic Diana gets to do even less. The first book was probably meant to be a standalone (like the Rambo series), but the concept is just too cool to leave alone. This second book is laying the framework and foundation for a truly epic series. Imagine an army of demonically possessed Terminators surrounded by malevolent ghost allies, and you won't be disappointed. Looking forward to book #3!

4.5 Stars.

THE EXORCIST CODE 2: Haunted, by William Massa, takes place after the events of book one, with Father Callum being asked to go along with a tech genius to verify the existence of ghosts--life after death. Full of twists, and new characters, I really enjoyed this installment.

I'm very excited to read the next in this unique series!

Recomendaría el libro : Tal vez...

Motivo: No tiene un final definido o la capacidad de ser autónoma. Te obliga a leer la 1era parte para conocer los antecedentes y la tercera parte para conocer el descenlace de la historia.


Continuaré la lectura de otras obras de este autor a la espera de la 3ra parte.
