Gatekeeper is a fun daemonic adventure through alternative dimensions and a diversity of daemons. The prologue sucked me in as a mysterious murderer brutally kills off what he believes is the last of the gatekeeper line. Rachel's character is strong, edgy and impulsive. I was very interested in the other dimensions and Rachel's dimension of Arcana. Arcana seems similar to ours, but with a better social structure. I would love to explore more of Arcana and how the people there came to be in charge of the daemons in the different dimensions. I also really enjoyed the human Oracle, Bach. I know that he probably has a great backstory, but it hasn't been explored yet. The riot daemon is a wonderful addition and I hope it doesn't get sent away just yet. I have a lot of questions about Apep and why a human would kill to have the daemon back on Earth. The ending was suspenseful and kept my interest up right until the end. There is definitely a lot more to explore in the series and I want to know what happens next!
