3.5 stars. I enjoyed the story and the world building and the pirates. Who doesn't like pirates. I also liked the concept of having 4 London that had varying levels of magic, which was cool to compare and contrast. I liked to the two main characters. I thought they had good chemistry and was so grateful to see a male and female character focus on the task at hand and not get all lovey-dovey. That was refreshing. However, I will say that at time this book got slow and was kinda boring. I put the book down for like two months before I finished it so yea. But I think it just suffered the fact of being the first book in a series because building the characteristics of the world takes time. One of the more interesting characters, Holland, makes appearances and I liked the illusions to his backstory, but the way he character played out in the book as meh. If he was such a beast that they alluded to, then I expected more. Overall, an enjoyable read with some flaws. Hopefully the sequel has a bit more action, and better usage of the characters. Yea. 3.5 stars.
