Noree grew, but never left her love for fantasy and horror. Her dreams pushed her and her hand itched to write the visions she saw.

An Archangel Behaving Like A Demon

Continuing from book 2, the Van Helsing Organization is still in NYC. Gabby is on a vengeance mission for John, when something else co.we along.

There is definitely a nice big twist close to the end, and its a good one. I wasn't expecting this little surprise.

We are introduced to two odd characters, Irae and Aaron. Then there's the Archangel Sariel, for me he behaves like a devil. I think k he has his priorities mixed up.

There is a lot of action in this book, and it is very fast paste. I sometimes tired of Gabby's inner voice, and her self pity, but she's been around a while so ill give her a break. Marge also is driving me a little crazy with her attitude. I still like both of them.

Overall, not a bad third book. It did keep me interested, and I flew through it. I just wanted to know what was going to happen next. I do recommend.

Gabriella de Lucca faces a new threat who turns out to be a powerful enemy on a mission to destroy everything. In an intense race to sever the ties that have them trapped nothing seems to work despite everyone's best efforts. For Esais Van Helsing, family comes first and that makes him a target that will affect everyone. The attacks are continuous, not only are demons being pursued but nephilims become threats and we wonder what Gaby can do now? Intriguing the situation of the protagonist, more losses weigh on her and she has not yet been able to exercise her revenge. Interesting, fast paced, suspense, strong emotions, violence, mystery, detailed descriptions and narrations and some answers to questions about the Van Helsings and Gabriella. The book’s end suggests a new twist in the story that I did not expect.
