The Unholy Trinity, Book 1 is definitely one for the books as it describes a possessed Sister Sarah and her treks of dealing with the paranormal. I found this book to be very well written with great character development. The stories are descriptive, creative and yet horrifying to say the least especially when she was on Italy’s most famous haunted island of Poveglia. I absolutely enjoyed this book and would definitely recommend it highly. I am voluntarily leaving this honest unbiased review of my own volition.
