An Intrigue of Witches

There was a lot going on in this one! I liked the secret American history thriller parts, but the villain(s) and their ultimate plan were a little over the top. I didn't mind the way it ended and the twists about identities. I didn't like the AI parts and I'm not sure that I understood what the ultimate plan was with those.
Overall this was a good over the top sci-fi thriller. It was a fun read.
