The series The Book of Spirit of Thieves is both a prequel and a sequel to Morgan Rhodes other series Falling Kingdoms. With it’s dueling narratives that take place centuries before and after and in the same realm as the action of her previous books and also in our own world in present time. In some ways, it fills the origin holes of some the mysteries and prophecies but stands on it own. The switching POV of Maddox, Becca, Crystal and Farrell are kind of a mix bag. I like Maddox as his is different from the others. It’s the prequel part of the story and takes place in Mytica. Becca, Crystal and Farrell are all in present day Toronto. The sisters Becca and Crystal are fine. There is a genuine love between them but a little bit of distance. Since the events of the last book, they both have learned a lot about themselves and each other and they are not sure what to do about this new knowledge. Farrell, I could do without, sort of. I understand why he is a POV but I just don’t really care that much about him as I do the others. He’s a privilege rich white boy who drinks and acts out because he didn’t get the love at home. He uses people to make him feel better and people keep giving his boorish behavior a pass because he’s just a good kid inside. He’s just hasn’t gotten over the loss of his brother. He’s being controlled by an ancient cult leader. Ok those are both true but still. I’ve over it. This series is fine and okay. I think Falling Kingdoms is a far more interesting series with more compelling characters and more twists and turns. That being said, it’s still kinda fun to read and it does fill in some wholes of the other series so it’s worth checking out if you’ve read the other series.
