This is good. I really enjoyed it and it hooked me from the start till the end.
I think I enjoyed Cardinal Giovanni Aldobrandini more and was so sad the way it ended for him. It was terrifying. Matteo is me (lol) cause I'm sought of an Atheist, but now, I'm rethinking my belief. Not that I want to be a Christian, but I'm thinking like Matteo. Maybe, there's a chance that there is God. So I'm gonna stick with Matteo and see how he unravel this dilemma in the sequel.
As for Adreana, this author developed her so well. The Hexagram (Star of David) and the book (when she glimpse a page from it). Her character was genius.
Although this story deserves a 5 star, I will be giving it a 4 star as there were some typos in it. Not many, but a very very very few. It didn't disrupt my flow though due to the engaging plot and how this author writes. But I'm pernickety.
Overall, A MUST READ!!!
